They won't align it correctly unless they pick it up with plates under the tires.
I would change the oil and then just work on getting the bugs out. Don't get crazy with the plugs and wires and all that. Tranny fluid and other fluis are good for a long time--engine oil gets contaminents blown in at every combustion. You might need your money for some repairs. Once you are settled into it, then work on the little things--wires, other fluids etc. Everytime I get an experienced vehicle there is a period of unrest. My most recent needed a timing belt, clutch, valve cover gasket, brakes and a few other things--these all manifested themselves over the first month. Now, maybe, I am ready to splurge and get some plug wires and fuzzy dice.
