Answer 1

In .vimrc add an autocmd for BufWinEnter to open all folds automatically like this:

autocmd BufWinEnter * silent! :%foldopen!

That tell vim to execute the silent :%foldopen! after opening BunWinEnter event (see :h BufWinEnter). The silent %foldopen! will execute foldopen on the whole buffer thanks to the % and will open all folds recursively because of the !. Any eventual error message will be suppressed by silent. (You could get error messages like E490: No fold found if the buffer actually didn't contain any fold yet)

Note: You could use BufRead instead of BufWinEnter but then if the file has a modeline that enables the folding that will override this autocmd. I mean BufRead autocmds run before the modeline is processed and BufWinEnter will run them after. I find the later to be more useful
