Razer keyboards are actually considered fairly bad, and having owned a Lycosa I agree with that. Everything else they do pretty well, love my Deathadder and have been using a Carcharias for years.
I would be looking into other brands like Coolermaster, Ducky, Corsair, Steelseries, Max and Das. They are much more well regarded when it comes to mechanicals and offers a lot more options in terms of backlight and switch colours than Razer.
Not many keyboards have wrist rests, and less that are actually useful. The only one thats any good that I know of the Corsair K60. But otherwise you can just get any number of aftermarket wrist rests, Ducky offer a leather one thats apparently pretty good.
I personally use a Ducky Shine II, definitely recommend getting a Shine III.
