My friends dilemna.

My friend just got a mac for free, he's not big on anything but games so here's what we want to do.

We've already started to find a way to run a windows emulator on his mac
1.We want a w/less way of routing an internet connection from his family windows PC to his personal MAC.
2.He wants to find out how to upgrade his mac to run this new MMO game I've downloaded, which I'll burn for him in good time, should he need to in order to run the game, if that's possible.
3.I know nothing about Macs and has only a rudimentary knowledge on all areas of PC's as it is, is there a site that'll let me learn what I'd need to in the future so I don't have to bug /comp/?

>>8 is completely irrelevant

Lets revise >>1, since it's been 2 days and I've gained some ground on the matter.

1.We want a way of routing an internet connection from his family windows PC to his personal MAC. Could an Ad hoc w/less connection be a possibility?

2.I'll get him to run some games on his Mac to check it's capabilities so dw about 2. for a while.
