You're not going to be able to keep much with only two bulbs.Maybe mushrooms and zoas is about it,sorry.Four bulbs like Yote mention will be more ideal.
For now,while your system is still young.I would test ammonia,nitrite,pH and nitrate weekly.Once everything stablilize,in another month maybe,test nitrate and pH weekly.
Once corals are added,testing calcium,magnesium and alkalinity weekly(in addition to nitrates and pH) is a good idea.
