1) Don't buy a new battery; from all indications you don't need it.
2) You might want to have an alternator output test done to make sure that the alternator is generating the output it should. You can remove the alternator, carry it in to the store and have it bench-tested there for free. (AutoZone, among other places)
3) The cables can be cleaned and reinstalled. Unbolt both from the battery. With some ingenuity and prying, you can back out each "captive" bolt in the end of the cable and remove it. This will reveal a metal inner ring, probably covered in goop and crud.
4) Use a wire terminal brush ($1.99) to make everything clean and spiffy in there, and also clean the underside of each bolt, where it tightens down on to the inner ring of the cable terminal.
5) Next, wipe a thin layer of Vaseline petroleum jelly on the clean metal inner rings and on the bolts, put the bolts and terminals back together, and button it all up. Positive connection goes on first, then the negative (ground). Make the bolts good and snug, but don't go torque-crazy or you'll risk stripping the threads of the battery.
