If your pump can fill both, just use the presta side. You'll need to get a presta valve tube for the new wheel. You shouild also get a presta to schrader valve adapter ($2) to carry with you in case you want to add air at a gas station, or if your pump is only schrader. Personally, I would eventually replace all my tubes to ones with presta valves. You should get an adapter nut ($2) for the front wheel if you want to run a presta valve in your existing rim.

You will need a 4.5mm spacer ($5) to put on the freehub to run a 7 speed cassette and a Shimano lockring tool ($8). Sunrace is a good choice for a 7 speed cassette. Go to their site and look at the options. Cheapest way is to get one that has the same tooth large cog so you don't need to replace the chain because it is too short. After 250 miles there is no reason to replace it now.

You will probably need to adjust the derailleur limit screws and the indexing. When you get to that point, you can check out videos or ask back here.
