First Grow, Need Help

So after reading this thread I see that I am making some mistakes on my first grow.

Let me give you some info:

I am going to be doing this in my closet. As of now all I have is a sheet nailed in 4 corners of the wall, making a box in my closet. I didn't notice this until today that my closet is alot colder then the rest of my apartment. I am using some seeds I got in a bag. I germinated them for over 3 days in a wet paper towel and came out with 11 (just check to find out I have 2 more sprouted) sprouting seeds. I planted them nearly 12 hours ago. I used medium size pots with miracle gro moisture control soil. I planted 3 in 3 pots and 2 in one pot. All I have for now is just one fluorescence light bulb. As for water, I just bought a gallon of some spring water and going to use a spray bottle to water the plants.

Now I did all of this before reading that thread. So when the stores open later on today, what should I pick up to help this grow go good? I'm guessing so far to buy 13 little pots and some basic potting soil but what else am I missing. Please keep in mind I have never done anything like this and also I am trying to stay on a budget. Thanks!

A LOT more light.

When the plants actually start to show, I am going to get 4 23w luorescence light bulbs which will hang over them and 2 tube ones to put on the side.

As of right now I took all the seeds out of the miracle gro soil and put them in dixie cups full of regular soil. Should I worry about watering them that much?

Just to note that I have 15 of them right now. Only reason why I have so many is since I always screw up stuff. Always good to have extras!

Once I get the growing down I will start a log on here. Woot!

Good idea to get them out of the miracle grow....I've heard some scary stories. Don't let your seeds drying, but not soaking wet either.
