Hi - I'm new to this and overwhelmed. Anyone want to help me figure out where to start? The things I'm particularly confused by are:

1. What's a good cent per mile rule of thumb? Looking to set up my own values for when something is a good deal to both earn and redeem flight miles and hotel (SPG for now) points.

2. The lingo - oh my gosh, the abbreviations! So much to learn.

And of course I'll take any other advice anyone cares to offer - just make sure a rookie can understand it. Thanks in advance for your time.
