SHOCK!! Its a powder you can buy at a pool store or chemical store.. its chlorine in powder form, you just dump it in your pool stir it up a bit, wait a day or two, and the pool should be clean.
First you have to determine if is in fact a painted pool. If it is a plaster pool then usually there is no paint unless it was painted because of age and damaged plaster. You most likely do not want to paint a plaster pool - have it acid washed to clean plaster. Not sure how to determine what type paint. You would have to have the paint chips anaylized to determine if it is a chlorinated base paint or epoxy paint. Ken
Yes you can (re-plaster) There should be a company in your area that does the plaster for pools when they are built and also re-plaster as they get older. Your Pool supplier should be able to suggest who may be the most reliable. yes,

Ph is up doesn't correlate with a clean pool. The pH needs to be lower to get it clean. And then you need chlorine, probably lots of it to get it clean; try 8 gallons of liquid or 20lbs of tricolor. Trichlor is good for white plaster pools. If you have a colored plaster, it would be better to use Dichlor.
Drain, pressure wash, and acid Wash the pool. If the plaster is old, it should be resurfaced. Resurfacing the pool will give you a new warranty and a longer life on your pool.
The fastest way is empty the pool. Be careful of temp and water table though.
