The pool will need to be cleaned again after you have used chemicals or a sandblaster. You can dispose of the stripped materials with a wet/dry vacuum.
If you want to resurface a concrete pool, your most economical choice is plaster. Certain products, such as Sider-Proof, actually make resurfacing in plaster easy enough for a do-it-yourselfer to tackle.
The tiles can be grouted once the thinset has dried. You can do tile installation yourself. However, if you have a pool you will need to make sure the plaster is in good condition before you can tile.
