Before I make suggestions on how to get cables in and out of existing walls, here are a couple of thoughts:
First, you say, "I understand everything about crimping". Second, you use the term "connector panels".
There is no mention of where the "head-end" will be. Are you thinking the office? If so, I would suggest you reconsider the plan. Instead of putting together a system that will serve you current configuration, put your head-end in the utility room or basement {*R1}, wherever you current phone and cable TV connectors enter the building. The idea here is that you will be creating a FLEXIBLE DESIGN that allows you and any future owner of the property a system of value verses a system of convenience. The wall plates (or connector panels?) will make a more attractive and reliable system. The cabling run back to the entry point will make it easy for you or future users to connect to your broadband medium of choice. Over the last 8 years I have switched from DSL to Cable Internet with minimal hassle because I'm cabled as suggested. My modem, router, VOIP, signal amplifiers, switches, etc...- all reside at the "head-end" of the cabling system, as recommended by the TIA, BICSI, etc...
As far as crimping goes, there shouldn't be any. Each cable should be TERMINATED to a faceplate on the user end and terminated again on the head-end. On the head-end you can terminate to a multiport faceplate or patch panel {*R2}. Then, use patch cords to make your connections. Hand terminated RJ45 connectors are a great source of failure and weakness.
About getting cables down walls (or up).
If your talking about cabling on outside walls, down is almost always easier, so if you have a basement or crawlspace you might consider working from there. Here's why: at the point where the hole will have to be drilled, in the attic you will probably be near the end of the trusses, where the clearance is minimal. There will almost certainly be no space for a drill to fit from above (even with a right angle drill or attachment), forcing you to drill from below (likely requiring that you open the wall) and leaving little room after passing through the wall's header before hitting the roof and possibly drilling through it! In the basement or crawlspace you will have a more accessible footer, above the foundation wall and your distance to the faceplate will be far less.
If appearance is not paramount and you must come from above, you might consider raceway {*R3}. I have even used short pieces of raceway (which looks much nicer) by doing this: 1) Drill a hole through the ceiling, really tight to the wall (this is almost always safe but look for electrical or plumbing first). Hints: a) Make sure you aren't drilling up at a stud, you need to be between wall studs. b) If you can, choose a location where there is no electrical. 2) Cut a 6" piece of plastic raceway (with adhesive), open it and drill a 3 / 4" hole in the back of it, close to the bottom. 3) Attach the raceway to the wall at the location of the hole going up 4) Open the raceway and cut a hole in the wall where your 3 / 4" hole is. This hole should about 4" from the ceiling and should make getting into the wall cavity a snap! 5) Feed the cable down the hole in the ceiling, through the raceway, and through the hole in the back of the raceway into the wall and down to your faceplate hole. This is where the chain mentioned in a previous post will come in handy {*R4} unless you need to fish through insulation. 6) Close the raceway, caulk around the top (at the ceiling) and put an endcap on the bottom of the raceway.
If your talking about inside walls, everything is easier! As already mentioned:
1) Get a long VERY SKINNY drill bit and drill up as close to the wall as you can. Hints: a) Make sure you aren't drilling up at a stud, you need to be between wall studs. b) If you can, choose a location where there is no electrical on EITHER SIDE of the wall - this will greatly reduce the likelihood of hitting any electrical wiring since the wiring (if any) will not be attached to the header except where it goes down to an outlet. 2) Locate the drill bit in the attic. Knowing that the drill bit is approximately 2" from the center of the wall, [1/2" of wall material + 1/2 of a 3 1/2 inch stud - adjust accordingly] move over 2" and drill a 1/2" or 3/4" hole (or a small pilot hole, if that feels safer to you) through the wall header and into the cavity. If you are using mudrings {*R5} and faceplates as I've suggested, you should have cut your faceplate hole first and put a flashlight in the hole before you go up into the attic to drill. This will give you a visual after you drill through the header!
Regardless of whether you are on an inside or outside wall, if possible, locate these holes where you can kill two birds with one stone. In other words, put two cables down the wall and feed one faceplate on each side!
On another note. This sounds like a lot of work. For little more cost, add home run cables for CATV and telephone (cat5) if it makes sense. If this is a house, a flexible design such as this will add value to a potential buyer.
Lastly, leave some extra cable length on each end of the cable. This used to be called a service loop but "loop" is not recommended in higher speeds of cabling. I tend to "snake" the extra cable.
