I think the downvotes are for such a subjective setup.

Other thoughts - if you find a full-size keyboard uncomfortable, and prefer a custom keymapping, sounds like you might like the Happy Hacking Keyboard and a mouse of your choice:

It isn't cheap, but the compact nature of it allows you to have your mouse hand much closer. CTRL/CAPS swapping is considered also.

A simple tenkeyless (keyboard ends before the tenkey) might be suitable as well.

Of course if you're happy with your setup as is, that's all that matters. As is the common view in this thread, do whatever works for you.
