Remap both of the keys next to the control keys (Alt/Option on the left hand; Command/Win on the right hand) to the Mac Command key. There's a handy extra key cap provided with my Advantage Pro that lets you put the same Command/Win key cap on each of these keys, so it will even look right. (Alas, that trand won't last; see below.)
Now remap Home to Option. Remap Page Up to Option as well. Now you've got Control, Command, and Option under both thumbs. The only problem with this is that total strangers who are trying to use your keyboard will be unable to find your Option keys, but who cares about them? ;)
This takes away your Home and Page Up keys. I like having Page Up/Page Down available, so I remapped Ctrl-PageDown to PageUp. So I can hit PageDown to page down, and C-PageDown to page up.
I don't use the Home or End functions at all. I remap End to Escape, the Escape key to Caps Lock, and the Caps Lock key to F9. Then I set up F9 in Emacs to trigger my own personal keymap and, lo, I have an entire keyboard full of new two-keystroke shortcuts that I can program. (e.g. CapsLock g g instantiates Magit; CapsLock s opens a new shell in another emacs window, CapsLock m opens a manpage, CapsLock j is dabbrev-expand, etc, etc, ad infinitum)
Do what I do:
(Here's the default layout for reference (ignore the Dvorak stuff for the purposes of this comment). Note the placement of the thumb keys: http://www.ergocanada.com/products/keyboards/advantage_image...)

Kinesis keyboards are fun!
