Game Patch Downloads and Steam Help

Pretty much copy pasted my thread from Alienware Forum to see if I could get any help with my patch/steam issues.

Ok so my M17 is likely to arrive in my hands after my unit has moved from our current location, and I most likely won't be able to get it connected to internet right away, if at all, and if I do it will be extremely slow. Right now at work, I have a decent connection, and can download from around 50kb/s to 80kb/s. Not terrible compared to my room which gets 0.5-10 kb/s. Problem is the internet here at work is blocked by just about every site out there, i'm suprised I can get on here at work. So I have no way to get on alienware to download anything i'd need to get, nor to download needed patches for games. I was able to find a few mirrors I could access. But I was wondering if anybody had links to mirrors for needed applications, patches, and drivers I need to make sure I get my computer up and running without an internet connection.

Also are there any tricks to install games such as Crysis Warhead, GTA:4, etc without having access to the internet? As well as tricks to keep Steam working offline, I can get it to work occasionally, but most of the time it says Game is not available in offline mode or it won't even let me open steam in offline mode on occasion.

Some games I could use patches for that I own are.

Company of Heros: Gold Edition w/ Opposing Fronts
Crysis Warhead
GTA:IV
Empire Total War
Dawn of War 2
FSX
Call of Duty 4
