Lion - help with two issues

Thanks in advance.

My first issue, which probably isn't a big one to most people, but I am a little anal retentive ... in Finder on SL it showed your hard drive free space...where can i find this in Lion?

Second issue, I downloaded Lion (obviously lol) and then had an update to iTunes and thunderbolt .... i downloaded both and have restarted on two occasions but every time it still shows the thunderbolt in my software update list. anyone else have this problem?

Thanks again!
