i'm not sure what you would need exactly for charging the battery, if you plan to use a solar panel you can get a solar charge controller online for pretty cheap. as far as series/parallel you could do that to reduce the current draw on individual cells, but i'm not sure how you would calculate that. as far as that link i posted, i know that starter would draw more than you car (most likely) but if you build your pack to handle that much it would work just fine for your car (assuming the draw is less)
