As long as you have steady income you should have absolutely no trouble financing a car once your lease ends. You can walk onto a car lot the day you get your discharge in hand and finance a brand new car. Your interest rate may not be fantastic, but chances are it will be better than it would have been while you were carrying all that debt.
Financing a laptop may be a bit more difficult, you may want to try to avoid this and purchase one outright. If not, then try Gateway, or even try to get a personal loan from a company like Capital 1 in order to purchase the laptop.
Main thing when recovering from Bankruptcy is don't rush out and get yourself back in the same boat again, because you will find that you will begin to get credit card offers again, you will be solicited by finance companies, and it will all be very tempting because it will make you think you are back on track creditwise. Be careful.
