Its good your asking all of these questions without jumping in. Good man. :)
Everything sounds good so far. I would personally not add the rock the first day. This is where you install everything, water test-it, make sure it works, ect ect. I would add rock a day or so after.
Do not add any Livestock untill your cycle is complete. CUC should be at least a few days after the cycle.
5% each week is a bit low. I think the cycle will speed up if you even perform this 5% change each day. You could also do 15-20% every 3-5 days.
Fish should be at least 30-40 days after the cycle, if not more. SW fish need a tank with the proper paramaters; this will ensure no one bites the dust early on.
