Use a fan, blowing directly between lights and plants. You won't need an exhaust system if you can leave the door to the grow room open. With an open window somewhere in the locale you should have enough ventilation. Buy a temperature gauge (sorry, went the long way there...), and make sure the temp' of the grow room stays between 78-80 f (I need a new keyboard, this one doesn't have a pound or a degrees symbol). It's not as hard as it sounds, for the first week of my grow the temp' was reaching 96f, which is bad, no, really bad. I managed to get the temp' down by opening the grow room door. Today the temp was down to 79f, but the weather in this country is getting colder. It's been, up till today, a steady 80f.
The best way to learn is to get stuck in, make mistakes and learn from them. It's the only way. With a little common sense you should be alright. This is your 1st grow, just relax and remember that what you are growing is a weed. In the plant kingdom the weed is feared, it will starve plants of their nutrients, killing them slowly so that there is more room for its brethren, and it's very will to survive is immense. With a few basic things your plants will grow, blue or red light of sizeable wattage, use flourescents as a bulk-up to your main light. Water and some natural fertiliser. Your plants will grow and your experience will tell, you'll want more: bigger, better plants.
