For your office, the SonicWall TZ170 is a very good wireless router for small and medium businesses, but you'll probably spend some time with their support folks setting it up. It is, however, a very robust solution for not a ton of money and without a Cisco label. What is your FracT1 terminated with in the office currently?
Vulcan's question is quite appropriate; if you have an in-house W2K3 server running Active Directory, you can hand off most routing duties to it directly, adding a wireless access point to the mix. But I'm guessing if your skillset is not very high by your own estimation, there's no server in the equation. If that's the case, you can just run an 8-port switch from the FracT1 termination point with a pass-through to a Linksys wireless access point. No need to make it more complicated than you have to...
And Linksys routers (WRT54G is a good one) work just fine at home, also.
