As I understand it none of the hardware forwarders
6500, 4500, 3560, 3750 ... can shape the traffic at less than the 'natural' rate of the output interface.
Oh on the other hand maybe you can. Change the ports to 10M and use whatever queuing they do. This will only work if the wireless rate is > 10Mbps real transfer rate. Otherwise back to square one.

3560 / 3750 can do some shaping on the interface, and then use SRR limiting within that.
limiting is limited to 90% of line speed at the high end, but i havent used any other settings.
you can enable priority on Q1 on the switch, but if you do that i dont think you can limit the outbound high priority traffic on the port.
the alternative is to use the SRR Q then set Q1 to shaped traffic for the portion of link speed you want - setting Q1 to "3" means it gets up to 1/3 of the bandwidth.
so port at 100M, limit the speed, and set the 4 Qs as you need them. then use DSCP or policies on inbound traffic to put the high priority stuff into Q1.
read the qos chapter of the manual - then when you get to the end read it again, as it is fairly confusing - the examples help.
the config is fairly messy, but most of the mapping settings are global, and once you work it out just cut and paste for other switches.
then finally - test it to make sure it does what you expect.....
