Can someone show me where to find a glossary that defines the tablature notes?

Try here.

Do you mean C = 5th fret 5th string?
That's something you've got to learn. How to know the fretboard without looking at it. But if you want you can always write the note in the Guitar Pro and you have the traditional notation above.
Let me know if that's what you've asked for.
About learning the fretboard I'm doing a 101 lesson, perhaps that would clarify the topic.

You can also check this legend we have on main tab of each lesson:

I think it's a D at 5th fret on 5th string

Thank you- that's exactly what I was looking for. I hadn't gone to the tab main page, I was only looking at the individual tabs as they were broken down.

Ok Doug, there are some other symbols for note values.
Guitar Pro uses this:

Duration Legend
---------------
W - whole
H - half
Q - quarter
E - 8th
S - 16th
T - 32nd
X - 64th

I don't use those symbols in my tabs anyway. Tabs are good for a quick reference about fingerings. The traditional staff gives you more info about note duration. So, it's important to learn both systems.
