Welcome, I am also fairly new to
SW as well. I have been keeping african cichlids for about the past yr. I just moved them from a 38g in to a 55g. Most of mine are from lake tanganikans and only 3 are from lake malawi, and a few loaches.
As I'm sure you have already noticed you will need to put alot more time, effort and $ into
SW. Waiting to get back form your trip is a good idea, patience was the first thing I was told about when entering this hobby.
And as far as I know current is good. DIff corals and anemones will require diff amounts or current and light. So simply place them in the appropriate loaction. And if anemones do not like thier location, they will relocate themselves. On the other hand you may find to much current for the fish. I have heard others say their fish only swim one way, kinda humorous for us, not so great for the fish. So just keep an eye on that. You should do just fine tho, it seems you have a good grasp on what to do. But I am no expert, just a humble apprentice.
Good Luck.
