If you are happy to learn from books, here are some suggestions.
If you want an introduction to elementary logic aimed at philosophers, John MacFarlane's "Philosophical Logic: A Contemporary Introduction" is a good start.
On modal logic, the standard text is Hughes and Cresswell, but it's fairly heavy going for a beginner. You might be better off with Rod Girle's "Modal Logics and Philosophy".
For the philosophical issues concerning the concepts used within logic, Anthony Grayling's "An Introduction to Philosophical Logic" is good.
For a general introduction to the philosophy of language, try Szabo and Thomason, "Philosophy of Language".
