Congrats on a wonderful time.
My fiancée and I also agreed to wait until marriage, and after 7 years we've probably done everything except sex
As for the "other things" you can't go wrong by starting with a massage. Of course you have to be naked for a proper massage, and things can easily heat up from there. After that there is mutual manual stimulation, oral, and a few others depending on what you both enjoy. But finding that out is part of the fun.
