Rack is a good idea if your room stays above 75°. Belly heat is probably preferred to back for adults. Herpstats are (IMO) the best thermostats to have. Build your own incubator. Unless you're looking at professionally made ones (like hot box etc) and willing to drop 500-1k on it. The incubators sold by big herp stores are crap.
Now...the really fun questions!
you say your albino is a hatchling, and you're planning on getting a clown girl (I assume hatchling also). Well, they will need to be 2-3 years old before they can breed. Which is the exact timeframe of you going to university. Are you going to be able to take them with you? Will you have the funds then to deal with feeding them? What about housing and feeding the hatchlings? Each girl could give you 8-12 babies (or more,or less) that's 8-12 more mouths to feed every week. Not to mention another rack and thermostat. (Unless you get a herpstat 4 from the get go)
Then you have to think about this: what happens if you can't sell the babies? Or only sell half of them? You have to be prepared to raise them until you can sell them.
One last thing, you're dealing with recessives, which are awesome and all, but people tend to be leery of buying hets from breeders without a reputation. They are taking your word that it is what you say it is. Now, having pictures of locks definitely helps that out. But still, they might be hard to move.
You will not make your money back on your girls or your equipment in the first year. Hell, probably not in the first five. So don't expect to.
Think this through and think of where you'll be in 2-3 years when these girls are ready.
Just my 2¢
