Trigger tables:

New Tables for calibrated Jets

 Level 1

Old tables for uncalibrated Jets

Level 1 trigger table for high luminosity (maybe not up-to-date?)
Level 1 trigger table for low luminosity (maybe not up-to-date?)
Level 1 trigger table for muons plus MET (maybe not up-to-date?)

Here are the guide-lines that produced the 100 Hz output for level 3.

Offline cuts:

Here is a summary from Daniel Denegri of the offline cuts  used in various proposed Higgs analyses

Here is a list of channels, with associated physics cuts and desired L1 cuts for lepton + jet trigger by Vladimir Gavrilov
