disregard my all my installation problems! a simple reboot and i was into LINUX!
Congrats!
Have you actually installed it now (over whatever was there before) or are you running it off of the liveCD (i.e. booting off of a CD and not having it on your hard drive yet?) The latter can be a very good idea to check it out, but it isn't the same as actually having it on your hard drive (and thus bootable without the cd, and also able to install extra software).
now the real puzzle...i accidentally logged off...but when signing back in, i used my same login username and password as for windows and it did not work...why not?
There really isn't a way for the Linux OS to know what your passwords were on Windows. At some point in the installation, it should have prompted you to create a username and password to use. ([edit later on] - Nevermind! Apparently it CAN somehow get usernames and passwords from Windows when installing. Freaky, it couldn't do that back when I first got it... it should have still prompted you about this during installation though and should have done it, no idea why it's not working.)
what cool things should i look for/download for linux? i see openoffice is already in, as is firefox
what about music players, instant messenger clients, etc?
I think Gaim should already be installed as an instant messenger client, that works fine for me.
For music players, you definitely want to get mp3s working - they can't distribute the mp3 decoder by default because of licensing issues of some sort, but it's easy to get working.
Instructions for how to do this in a simple way can be found here:
http://www.psychocats.net/ubuntu/mp3 . (DISCLAIMER - random tutorial from the web, in no way official. But the site seems to have good instructions for things, and it seems right to me.)
To have access to all the software that is around, you might also want to follow the instructions in
http://www.psychocats.net/ubuntu/sources - the part that says "enabling extra repositories the point-and-click way". (Likewise disclaimer because i don't know how current or how correct it is, but those instructions look like they should be right and they don't tell you to do anything that could screw things up)
From what I remember, the default media players that come with Ubuntu aren't that great, so if they don't meet your needs getting something else (VLC?) might be a good idea. But on the other hand, rhythmbox is good enough for a lot of people, I think that comes by default? (Check the applications -> sound and video menu, there's media players there.) So that might be good enough.
Really, if there was anything that was absolutely a must-have, it would probably be included already if it was legally possible, so there isn't too much to recommend.
You can try asking on ubuntuforums.org , there will probably be more knowledgeable people there than here. I'll do my best to respond to things you ask, but I can't guarantee that I'll get to it quickly - you made this post at 12:07 AM eastern time, after I'd last checked this forum before going to sleep
Also - richw76 suggested looking at sourceforge. I would add in the suggestion that whenever you install something, it's much better to go to applications->add/remove OR use system->administration->synaptic package manager (or, if you end up being a command-line guy, apt-get), and finding what you need through those, if it's there, rather than using the instructions online for compiling or installing things manually. It's more reliable and easier to manage, especially for upgrades or uninstalls later on.
On the other hand, if you want to really dive in and get into the nitty-gritty of things, then it's probably a good idea to get involved in some weird not-officially-supported projects that do what you want better than the official ones, and learn to use the command-line for these things instead of the GUIs, but I think the folks at Ubuntu have tried their best to make sure that, as much as possible, this isn't actually required to use Ubuntu. So without knowing what your goals are with using Ubuntu, hard to give any specific suggestions.
