If you choose to understand Javascripting and use it in your forms, I admire you. You might try javascript.internet.com for some good cut and paste examples, and you'll learn by experimenting. You should still find some good tutorials so you can learn the logic behind the syntax, email me when you find any good tutorials that explain HOW it works.
If you have such tasks as simple math calculations and password double-entry for verification, these are all things that should be taken care of on the client side if you want to be professional. We're talking about 1K of code for most of these things vs. another unnecceary hit on the database or php server.
