Ideas for my first grow. Help appreciated.

Hey guys I'm just another newb with some newb questions and concerns about my first grow!

I've been researching for quite a while and I think I'm more than ready for my first grow once I have the funds to finish off my grow tent. Just a few questions and things I would like to get straight first before I even think about investing real $ into this. I plan to get feminized auto flower seeds (undecided on strain) and I plan to grow 6 small plants at a time out of a grow tent placed in my closet http://www.htgsupply.com/Product-Grow-Tent---Mother-Keeper-51.5-x-22.5-x-48.5---Silver-Lined.asp. I will be using 250w MH with 6" cool tube reflector (switching to HPS at first sign of flowering, remember auto flower ) directly over the plants and I will have 4x 150w CFL lights (2x 6500k 2x 2700k) in all 4 corners via clamp on heat lamps that I will be able to move along with the MH/HPS light according to plant height. I'm assuming I'm better off hanging the CFLS to penetrate to the mid/bottom of the plants and not the canopy since the 250w will be directly above them? As for light cycle I was thinking either 24 hours until flower then 20 hours of dark switch to HPS and go 18/6 until harvest or 18/6 the whole way still with the 20 hour dark period and switch to HPS at first sign of flowering. I will be able to exhaust out of the tent using only intake/exhaust fans I believe I can use 4 with this tent and I will have a household oscilating fan inside of the closet on the tent, but I have no way to actually vent the air from my closet outside. I have central air and there is a vent in the room directly in the middle of the ceiling. Assuming I can keep the temp and humidity straight with just venting out of the tent into my closet how could I get clean air in? crack my window 3 hours a day and hope for the best? For nutes I will be using Canna - Rhizotonic, TerraVega, TerraFlores, Cannazym and PK 13/14. As for when to start introducing which nutes and when that's something I still have to look into for auto flower strains. My main concern is being able to vent out of the tent but not being able to actually vent out of my closet, the closet has sliding doors and one side can be kept open if needed.. With 850 watts in there I'm guessing it may be hard to keep the temp at 70-75 even with central air running. I'm sure there are plenty of things in my plan that need to be revised and thanks in advance to anyone that took the time to read.

p.s. Do people generally top/fim plants from auto flower seeds even with the fast grow time? Topping/fimming is something I would like to play with during my first grow, at least with a couple of them anyway. Also, I'm guessing that using heat lamps for the CFLS may be a bad idea cause it could cause heat spots? If so what would be the cheapest and most effecient/cost free way to hang 4 150w cfls... one in each corner of the tent, preferably without having to buy a 50$ fixture for each CFL, thanks again.

just get regualr auto seeds.
6 plants need a 400HPS or even a 600
use the HPS for veg and flower
18/6 is stil veg
12/12 is for flowering
your 850 watts may seem like a lot until you actually look at the lumens you are putting out.
i would suggest getting a book or two on growing, jorge cervantes or ed rosenthal.

So 67,000 ( more than 10,000 per plant ) lumens not enough for 6 small auto flower plants that wont break 2 feet? Why would I not get fem seeds when only growing 6 plants total? Anything I've read, and that's a lot, says that Auto flower seeds negate the need for a change in light cycle to force the plant to flower, so it's either 24/7 veg until flower, long dark period to get pheromones or w/e going (20-30 hours) switch to HPS and go 18/6 until harvest... Or 18/6 OR 20/4 the whole way, I've also read things that say anything more than 18 hours of light a day will be wasted electricity but I think that's probably false.. I may use the HPS for veg and flower because with the MH I drop to 54,500 Lumens... So I'm guessing I should use HPS the whole way to stay at 10k+ lumens per plant? This is just what I've been reading the past few days, and I've never heard of a 12/12 light cycle with auto flower strains. Again my main issue is being unable to vent my closet with an MH running in there... Will just venting the tent into my closet be okay as long as I get clean air into the room?

P.s. Scratch that I will be using 400w MH for veg switching to 400 HPS at first sign of flowering since I'll actually be paying 3$ more for the 250w (same brand and both HPS with MH conversion buld, makes no sense). Now I'm more concerned about heat.
