Installing a new shower stall is a very simple process, they are relatively inexpensive and usually come with easy to follow instructions. However, if you have had leakage, you may run into some structural damage behind the walls of the shower (probably just confined to the gypsum), the damage in your pictures appears to be just the caulking and you could just remove it and clean up with bleach or a mold remover, i wouldn't recommend using a chemical to remove the sealant, as this may damage the finish on the door and walls. If you do remove the shower and notice water damage to the walls under the shower, I would recommend replacing them with a cement backer board like 'Hardie Backer' or 'Wonderboard'. The 'Green" drywall that was common is not actually waterproof and will eventually absorb water as only the outer paper is waterproof.
Good Luck!
