few things you don't mention, like room size, or grow style.
Venting is going to be your biggest concern, and short of a tent, you'll need to pull air out of the room, and have at least a passive vent to pull fresh air in from. Odor is a potential concern here, so if you're not legal, don't skimp on that part of planning (look into carbon and ozone to start). If you are lucky you have an air cooled hood, which can require a little more to setup depending on your space, but have some major benefits (not the least of which is preventing chunks of heat from ever entering the grow space). In general you would calculate the cubic feet of your room, and determine how much turnover per minute you want, then it's just simple math to determine the CFM fan you need (and probably give yourself 10% extra to account for ductwork loss). There are actually some online venting calculators, as well as greenhouse venting calculators that work quite well for our purposes, especially if you know the starting temp and target temps.
On soil, my preference is to go with potting soil or topsoil, the real stuff, not the mixes that have nutrients added, just pure topsoil/potting-soil. I use 3 parts soil, 2 parts small perlite, and 1 part peat. You can also add organics like guano and worm casings at this point too. Realize the ratios are determined more by target PH than by anything, and were reached after playing around a little with the ingredients we get locally. Some people will need to add lime and other things to buffer for PH as well. That should give you a starting point though.
How to set this up is something you really need to think more on though. Personally I would try to setup something perpetual, but if that is a 4 tube t5, then it's not going to veg what you'd need to keep the 1000w efficient (imo at least). If you didn't require as frequent harvests, or the room is to small to split into a veg/flower areas, you could consider using the t5 as a supplemental light (maybe move it around illuminating one side of the room per day), or you could do a tray of small clones in a sog under that to flower. With more T5's, or the T5's to start and a 400-600w MH for middle to late veg, you could setup a perpetual that would produce quite well growing 4-6 larger plants.
Another idea, and something to seriously consider, is a scrog (screen of green). If you're not familiar with them, look it up, tons out there on them.
