Sorry, but this is not correct. The note before the slash indicates the chord and the note after the slash indicates the bass note. C/G indicates a C chord with a G as the bass, for example (which, if your uke is strung with a low G, is technically what you're playing when you play 0003...in reentrant tuning you're playing a regular C). If you search the forums for slash chord you'll find several discussions that go into more depth as towhy it matters (the most recent is here: http://www.ukuleleunderground.com/forum/showthread.php?t=14308). The bottom line, however, is that while these chords are useful for guitar (which has two extra bass strings) you can usually ignore the bass note on the uke and just play the chord indicated by the first note.
Sorry, I missed that. I've never seen that before...do you have an online example you could provide a link for?
To the best of my knowledge, yes (they're the same). They should both be capital letters, but I think some people use lowercase for the bass note to make the chord stand out.
OK, in this case it's indicating that you should change the bass note. So you're playing C and then C/B where it shows /b. If you notice you're then playing D/A and G so the effect is that the bass note is walking down from C to G. This is the primary reason for using slash chords in the first place...when you want a specific bassline. You can't achieve this effect on the uke unless you're playing with a low G string, in which case you still have to move a few chords around: C (5433), C/B (4433), D/A (2220), G (0232). Notice that on the G string (your bass note) you're moving from fret 5 (C) to fret 4 (B) to fret 2 (A) to the open string (G).
