Few questions... for the branch offices, how big are the subnets? If too big (i.e. larger than a single class C), may need to vlan... this also depends on the LAN traffic and apps (IPX SAPs, etc).
The same routers that you use for WAN routing via the fractional T1's can perform inter-Vlan routing via sub-interfaces on the eth int (there may be some limitation if the IOS is old or you are dealing with leagcy equipment). BUT, remember it makes no sense to vlan if the benefit you gain from segmentation is outweighed by the extra overhead on the router... so you really need to analyze that LAN traffic. Also, the previous poster stated...check those port counters for errors, like FCS, CRC, etc. This may indicate cabling plant issues. Last, I would suggest using the "set port host" command instead of portfast on all ports not connected to other switches or routers. Hope this helps.
