I want to store my iTunes tracks as mp3 files so that I can then use them in a video editing package that does not recognise AAC format. Therefore, is there any real noticeable difference between mp3 format and AAC when ripping CDs into iTunes?

Nope, I've never noticed a difference, and I have tried it out with the same song with the two different formats. It was Iron Maiden - Run to the Hills (from CD).

Completley depends on the bitrate.
 
AAC is generally regarded as a superior compression format because it's based on the MPEG4 standard. This means AAC is better quality to the equivalent MP3. It really does depend on your quality of hearing and what bit rate you use. AAC is noticeably better around 128K-160k but 192kbit and above the difference is barely noticeable.
 
Filesize = Bitrate x Length of Track,

For example;

128Kb/s x 240 (4 mins) = 30,720Kb

30,720Kb /8 = 3,840KB

So a 4 min song running at 128Kb/s will be 3,840KB, + a few bytes for container overheads.
