As far as the bid pack, you should of been briefed in IOE. The 727 and 10 S/O LCAs are the best at this. If you went directly to a right seat, you may not have received as much info, since those guys are more accustomed to instructing guys that have been around a while.
All that said, if you compare the bid line to the pairings you can start to see and figure out most of this stuff. Ask guys you fly with if you have questions. Most of it makes sense once you have lived it for a few months.
As far as VIPS, it changes, so you still have to get good at clicking to find something. Take 10-15 minutes and click through the entire site when you aren't under the gun to find something quickly.
