Good to know you've got the equipment
Is the filter for sitting inside the tank or outside?
Your tank is going to be too shallow for angels (I'm guessing its 36x12x12") and, tey are Cichlids so can get quite aggressive as they get bigger.
I have limited experience with Cichlids, but if you want some for your aquarium, Apistogramas & Kribensis etc. are good starter ones, that 'should' get on with most community fish.
OK, planted is good, you'll need to decide what type of planting you want to do, as a 'starter' setup, the hardier plants are probably better, Java fern/Java moss tied to wood is very hardy! and things like Elodea (or other simple stem plants) inserted into the gravel can do well in good light.
Perhaps see if you can get hold of some bogwood (or mopani wood) - I believe pets at home have a '3 for 2' offer on at the moment.
Do you have a stand for the tank as well?
