Glancing over the cheat-sheet, it looks like the only major change would be the fact that right-paren is not mapped to jump-outward; instead, I just use the right arrow for that (when there are intervening chars, I  use opt-up opt-right).

Backspace usually. Yes, currently `undo' removes only the left parenthesis.

Also, sometime I forget to put parens in some of the the `match'
clauses and realize it while/after writing the clauses. Then I select
the clause and put the left parenthesis, which automatically puts the
right parenthesis as well. Is there a way to put an empty matched
parentheses and then add statements into it from left or right? (like
the slurp/barf commands in paredit)
