chuck, 3g network is internet, tethering is using the phone on the computer to get internet. Doing a quick google search i found the download on 3g ranged from 500kbps to over 1000kbps with uplinks ranging from 200kbps to over 700kbps. Everquest needs a 28.8Kbps link as says the system requirements. What cant you google....
Btw depending on if you work for a medium to large sized company, they most likely have a policy to prevent what you are doing. If caught you could face disciplinary action up to and including being fired. I know people who used applications such as logmein.com to remote into their pc at home or play their psp at work, they got fired. I know this because i have worked in IT for a while and know how IT policy is applied
