I don't think either is possible with the current code.
Re. item 1: You can selectively render formulas by limiting the region
to a subtree, so it should be possible to do what you want by adding a
couple of functions and coming up with a decent user interface.
Re. item 2: this is done unconditionally in the function
org-ctrl-c-ctrl-c (in file lisp/org.el) and although I don't know the
reason, there probably is one and it's probably important[fn:1], so you
should proceed with caution. If you want to experiment, I'd suggest you
start by commenting out the >>>>> marked line <<<<< below in
org-ctrl-c-ctrl-c and testing extensively to see what breaks:

Cheers,

Footnotes:
[fn:1] I suspect that it's a necessary precondition for some of the
*many* things that this function does, but I don't know for sure.
