ok i'm downloading mysql tools to use instead of navicat, I only got that one cause the guide said to use it.

Mysql query browser is pretty easy to use, you simply point it to the machine where the database is hosted and you choose the database you want to look at. Once the database is loaded up in the browser you'll see the different tables on the right side. You can double click those to show the different lines in each table. At the bottom of the window there's a small edit button, you have to click edit and then you can alter fields. Just make sure to save the changes you make.

Good idea to back up the database first since your new to editing... mysql admin is good for backing up.

is there a listing of what does what, this is like being given a book in a foreign language and asked to read aloud

Mostly it's self explanatory, or theres a short description to the right... It would help if it was alphabetical, but it's not :)
