No beating around the bush. Here it is. I may add hints later but I doubt it'll be necessary; the built in ones should do the trick.

Oops forgot to say, $30.01 contributor required.

Fine, lazy people.
1), I bought the bethesda pack, duh. I didn't pay full price either. There was a code, something about being a geek.
3), Deal wasn't open long, and the site was getting hammered. If you'd waited for the hints (1 hr) then you'd have seen that it was "Not far off a full workday". Should take you two tries at most.
4), my friends list is pretty easy to locate. Click a few profiles and you'll find a comment from the stalker. Then it's just copy and paste.

I wasn't just gonna GIVE it to you, otherwise I'd just make a public giveaway. But now I have. :p

OK finished. Answers were:
1) $27.32. There was a 5% discount code IAMANELDERGEEK which made the pack even cheaper.
2) 29. Not many good things to be said about Rogue Warrior.
3) 6.
4) "(ØCĐ)™ ÇÏty_Spud {D/G}©", as a safeguard the word "spud" would also have worked. He's posted a rather amusing diatribe on any publicly-commentable profile for anyone on my friends list. I can't even remember why I blocked him, presumably unsolicited group invites. :D
5) dancing pigeons - ritalin

Getting all those right would have given you the link to http://www.steamgifts.com/giveaway/IECTS/rogue-warrior
