I'm not sure what caused the battery to get wet unless is was overcharged by the alternator which could have damaged it. However, to answer your question, there is nothing you can take off the battery to make it start. Additionally, the terminals don't need replaced unless they are damaged. Most times they are fine.
As far as locations, I don't know where you are located. If there are any nationally recognized parts stores such as Auto Zone, Advance. They will both test the battery and the alternator for you free of charge and install the battery free.
If you have a friend or someone who could jump start the car for you, then you may be able to drive it to have things checked and replaced.
