Hi, cooljay.
That's the thing about forums like this. (Especially when you have a decent bunch of members.)
When you show determination to use, and gradually master Linux, people will help.
The main thing to remember, with all Linux distros (as with any OS, really), is to get the house-keeping stuff out of the way first. And that includes the firewall. In Linux, that's really the only thing you need. No AV here.
When you do start to 'customize' things, you'll be astounded at the possibilities. Take a look at some of the stuff in the 'Show us your Linux desktop' thread, if you want some inspiration.

Those of my own desktops that you see, it's all my own work. I've had an interest in graphic design for a very long while.....every one of mine is built, by me, from the ground up. About the only things I Google for are the background images, and the PNG icons. But that's just the tip of the iceberg.....
Ask some of the others about Compiz, and 'the Cube'. And remember one thing; Linux has had all this for far longer than Windows has.
Get the chores out of the way first, then we'll help out with anything you care to ask. Have you had a chance to look through that Lubuntu 'check-list' yet?
Mike.
