For mice, are you palm or claw grip?
If claw, get the zowie fk or am
If palm, either DA(no 2013 version, synapse is shit) g400s(I'm pretty sure they fixed the problems, but as long as you still have the original receipt, they will replace broken mice). Other than that, get the zowie ec1 evo.
For the keyboard, either go all in or a cheap one. If you can't afford a 60ish dollar Cooler Master Quick Fire Rapid or any of the other CM storm mechanical keyboards which go on sale frequently, just buy a $10 logitech rubber membrane keyboard, and use that until you save enough for a mechanical.
If you do go down the path of a mechanical, first buy a switch sampler to pick your switch of choice. Buy the WASD sampler, and figure out which one you like the best.
But generally speaking, reds are best for gaming(get blacks if you have strong fingers) blues are best for typing (get greens if you have strong fingers) and browns for in between (clears for stronger fingers)
If you want the keyboard now, for reds:
$40 after 20 MIR
$60 after 15 MIR
