I think that it should behave much better now, please give it a try.
Also the problem in comment lines should be gone, hopefully.

Good opportunity to plug cdlatex.el. If you have it installed and
then turn on org-cdlatex-mode, one of the many things that will work
then is:
You type
l r { TAB
and get
\left\{ \right\}
with the cursor in the middle.
Similarly:
You type
f r TAB
and get
\frac{}{}
with the cursor in the first set of braces, TAB will move you into
the second, and then out.
If you are using a lot of math, this should be quite helpful.
Cheers
