Part of the keyboard journey is trying many different switches. You are now trying blues. It might turn out that you prefer stiffer switches. I do - I started with blues and reds, and now prefer greens and blacks. And buckling spring.
A wrist rest should only be used to rest your hands between bouts of typing. If you're not sure where to put your hands inbetween typing, maybe a wrist rest is what you need. You can try with a simple folded towel or a low profile box if you have one, just to see how you go typing with something in front of the keyboard. Personally I don't do that much typing, and I've got other things on my desk at home and at work to keep my hands busy while I'm not typing.
