One more thing:

I have had lettuce and spinach seeds sealed in a refrigerator for two years, and I have had seaweed and fish emulsion in my garage for two years, should they still be good?

That light is made to be installed in the ceiling (as in recessed) and hard wired. Look through the thread I've linked to on this page entitled "Post Your Grow Light Setup". I'd get 2-2 light fixtures for around $20 less.
I'd shop at

for the flats and trays.

Not sure about the lettuce seeds but your fertilizer should still be good if tightly capped. I wouldn't smell it though! lol. Never hurts to try with the old seeds. Give them a germination test and see what kind of rates you get.

Thanks for the advice! I have already ordered my flats and seeds. I decided that I am going to build a setup like the one"biradarcm" has made. I am going to splurge for a five shelf bookcase and attach shop lights to it. I will be using four flats. Each one is 11 inches wide and 22" long. If I set them up widthwise and use two shelves, do you guys think that one two-bulb shop light will work for each shelf. In other words, will two bulbs cover 11 inches in width?

I also am not sure about my soil. At home depot, they carry Miracle gro organic potting mix. Would it be better to get a high quality mix at a garden store or will that work?
