Wireless Setup- Now For The Network...?

Ok so here's what my current situation is:

For now I'm having my iMac connected to the Linksys WirelessG Router.
The PC has the wireless card in the other room. Internet works fine.
I want to share files between the two.

Where do I go to connect the two so I can transfer files. I went to the "Go"> "Connect To Server"...but it only shows my iMac, not the PC.

How do I get this setup?

Sorry, scratch that...it just showed up

But it shows the folders Local, MSHOME, and WORKGROUP. When I go to MSHOME and it shows the PC, it says to enter Username and Password for the PC (SMB/CIFS Filesystem Authentication). What do I enter? Is the this even the folder to share files with?

Ok the Adm. can DELETE this thread! I've figured it out!

WOW this makes me appreciate Mac's sooooo much more..
I did absolutely no configuring with my iMac....But the PC on the other hand required a lot of unwanted setups and configurations..
