Hey lisanorcross,
Welcome! Here's one blogger's (Frequent Miler's) approximation for point value: http://boardingarea.com/blogs/freque...rading-prices/

As for lingo, check the glossary: http://www.flyertalk.com/forum/glossary.php
You'll see people refer to airports by code (ATL = Atlanta, IAD = Washington Dulles etc). You'll see people refer to airlines by their IATA code (UA = United, WN = Southwest, etc).

Read lots and learn lots. Don't fret!
