Networks

would it be possible if i network/interconnect the following devices to create a Small Office Wireless LAN:
1. Sun Fire X2100 (running as Mail Server(Internal)/DNS Server/Proxy Server)
2. Linksys WRT54G Wireless G Router
WAP54G Wireless G Access point
WUSB54GC Compact USB Adapter (connected to
20+ PCs)
WPS54G Print Server Device
We will also acquire a mail Hosting service provider and a domain hosting service provider...

Will it work? What are the possible outcome? What might be wrong?
This is for our thesis...
