1. What will happen if there is a song with no id3 tags? will it just not show up? will it show up in the search? How willi play it?
Try it

. Most of the column headers, like title, "fall back" to filename if the tag doesn't exist.

2. Is there anyway i can get FB to change the location of the mp3 file when i change the artist tags etc?
3. Is there an iTunes feature that will copy anything played into the correct subdirectory of "My Music"?
These are related. And the short answer for both is No. Foobar does not automatically mess with your files. You need to TELL it to move the files. (File Operations -> Move).

4. Can i disable songs? eg, untick them in iTunes? I have some songs on my pc that arnt mine.
I don't know how this works in itunes. What is the benefit of disabling songs? Can't you just, not play them?
Suggestions:
1. Upgrade to 0.9.5.3 . You're missing out on some seriously awesome features (including the ability to create queries that depend on time.)
2. Check out the Optional Components. Take a look at the Optional Components offered (there's a link at the foobar2000 official site), don't forget to look at the components developed by kode54, foosion, haali and musicmusic (links in the Optional Components page in the official site). Also scroll through the 3rd party plugins page to see other 3rd party components.
3. Take a look at the FAQ (both official, at the foobar2000 site), and the
unofficial one.
4. Learn some titleformatting (take a look at the titleformat reference file that is in your foobar2000 installation directory).
5. Learn to create queries (take a look at the query syntax reference file that is also in your foobar2000 directory).
