newbie needs grow room setup advice

I have a 14x20 room in basement
1 1000 watt digi ballast & 6" air cooled hood 1-1000mh 1-1000hps dual arc
6" carbon filter with yo yo's
Roots organic soil and Heavy 16 nutes
8,000 watt window air conditioner with on off timer and humidity setting which could be put up high in egress window
Mostly everthing i need to get started

My plan is to panda wrap up a 10x10 area for flower and sectin it off with the intention of adding 3 more 1000 watt air cooled setups over 6 week period. Not enough $$ to get it all at once. My inline 6" fan is 426cfm.
1- is this enough cfm to cool 2 1000 watters. 1 for each to light setup??
2- Best way to set up room? My basement stays pretty cool as i live in lower michigan but im sure ill need atleast a 14,000 btu air conditioner by the time the setup is done.
3-best way to intake and exaust?? Is passive okay and if room is not completely sealed utilizing passive intake do i have to worry more about bugs?? Eventually will add co2 and seal it up tight when $$ is right.
too much brainstorming heads gonna explode. Any advice would be much appreciated. I do have more rooms i could veg in but could use the rest of the 10x20 area for this and put my mothers n clones in one of these smaller rooms. Advice please for a newb....

I'm a new guy too, but I'm pretty sure in order to avoid parasites you shouldn't go with organic soil, I heard you should go with sterilized soil. I could be wrong, wait with someone with seniority on this site to chime in.

those two fans should do the job as well as having the ac, I've used roots organic 707 soil on my last two grows and never had problems with parasites, I also use roots buddah bloom, budda grow, peak, and big swell nutes.

Thanks dubba, this is my first grow so any advice would be much appreciated. Ive researched to the point that my head may explode. Whats ur opinion of Heavy 16 nutes? Also i was in my basement this morning and it looks like the place had a serious termite problem at some point. Any suggestions, room will be totally sealed in panda except for passive intake. Do you think this would be a problem for the termites?
