You can turn F key control via the System Preferences, which I found make life easy. Also if you do do that it makes using the Expose keys (F9-F12) very handy (thats if you havent found them already it took me a week too).

Just one more tip (along with some bad, shameless self promo) I've got a post up with a set of links for newbies like us just to help get the feet on the ground. :) http://www.andyjarrett.co.uk/andy/blog/index.cfm/2...
If you do have a look and see anything i've missed drop a comment.
One of the other cool things I love about FireFox (among many many things), is that with the Web Developer extension, you can update the Source of the page and the page will change in real time without refreshing.
