Immigration alphabet soup

[no1]

I just discovered this website. I'm having a hard time to comprehend all the abreviations used. Real example, edited:

EB3, ATL-GA, PD - AUG 01,
140-485 RD - xxxxxx
140/485 TRX Miami (mistake) - xxxxxx
AILA inquiry - Case recalled - xxxxx
1st FP - xxxxx
2nd EAD & AP RD - xxxxxx
2nd EAD TRX xxxxxx



What's the best way to get a quick start and begin talking the same language as everyone else? Is there a primer for this alphabet soup somewhere?

Note: I'm on an H1B, the greencard is pending.
