I'd suggest the 2013 edition of the Naga. It's a redesign that makes the mouse itself as well as changing the thumb buttons to mechanical, so that you can actually *feel* when you've pressed it. I have the left handed edition myself. Trust me, it comes in real handy for FPSs. Keyboard wise, with I could help out. If you want space saving, as in a ten keyless one, there's the Cooler Master QuickFire series. They do make full size in it as well. Also, they sell them with your choice of Cherry blue/red/brown/green switches. I'm considering the CM QuickFire Rapid myself.
From what I've seen, the bonuses stick around right up until the release. One thing you could do to offset the cost a bit is to add to your steam wallet over time, like $5-15 here and there. I'm really bad about doing that with multiple credit cards to build up my wallet.
Either way, you'll be good if you have to wait a couple days before release. The only other thing I can suggest is to check their forums or email them
