Help setting up wireless LAN to cable modem

I want to bring cable (Comcast) broadband service into my home office. The cable company says pulling the cable will be a problem. That got me thinking about wireless.

Is it possible to have them install the cable wherever then get a wireless router to provide service to the whole house?

Will such a setup be as fast as being hard wired to the cable for internet access?

Can it also serve as a wireless LAN?

Will it be as fast as the cat5 LAN we have now? I think it's 100/10 or

10/100 or something like that?

Can anyone suggest good hardware? I don't want the cheapest. This is for a small business. I am willing to pay more for reliability and speed.

We have two computers -- one laptop and one workstation.

From what I've read, I just need (a) a wireless router, (b) a PCI wireless card for the workstation, and (c) a wireless PCMCIA card for the laptop. Anything else?

I may get a new laptop, so the wireless will be built in, right?

I am assuming I want to get 802.11g, right?

Any other considerations?

Thanks
