I understand that is is much more personal preference but I figure suggestions will point me in a direction to explore.

Suggestion on mouse and keyboard?

As expected I'm coding a lot more now that I have a job doing it but that also means more hand and finger fatigue, stock shit just ain't cutting it.

In regards to ergonomic mouse experience: I do like the contour red mouse alternative, as it allows the hands to remain at the keyboard.

It's just a tad^w extremely expensive.

You'll have to use a "normal" keyboard with that one anyway, and here I am very content with the Cherry MX 3.0 series. (I use blue, clicky switches.)

Razer death adder and any mechanical keyboard. Dunno why, but I've never found a mouse that's nearly as comfortable to palm than that mouse, it fits my hand like it was specifically designed for it (smaller hands). The lights are unprofessional though :s
