PHP navigation/user pass help

It goes without saying that I love this help, and I appreciate ALL the help everyone gives me. We are currently having big time budget cuts in my city, so I am hoping this website will put me in a better light than others.

ON TO MY QUESTION...

I have the fire rescue squad template (as most of you know...lol).

I'm trying to do 2 things right now that I need help on:

1. NAVIGATION - My navigation links at top...i'd like it to where I can mouse over it and another navigation thing pops up. Hard to explain. Like you mouse over and then a box of more links comes down. This way I can group some pages (i.e. stations & apparatus & etc) and be able to create a more full site and more expandable options.

2. USER/PASS - I would like to make it where each fire fighter, emt...etc has their own username and password and they can log in. and few stats I put on their site...etc.etc I think this is doen by PHP? No idea...I've been searching for 2 days.

I'm a novice, so you have to speak to me in 2 year old talk

Thanks for ANY advice, suggestions, or help!!
