Why would it be OK to say "provide confidential advice" but not "provide confidential help"? To me, the latter form seems wrong, but I can't explain why.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. See the FAQ for guidance on how to improve it.
Advice: "an opinion or recommendation offered as a guide to action, conduct"
Help: "to give or provide what is necessary to accomplish a task or satisfy a need; contribute strength or means to"
So I would provide confidential advice in a business to business situation, but I would provide confidential help with my friend's homework.
Both are correct grammatically, but the latter is probably used less often (there aren't as many situations where help need be confidential).
