The biggest indicator that you have an issue is worms packing up and getting out of dodge. They will literally climb out of the container and you'll find them half way across the room all died up and shriveled. If things are good, they will stay put.
Furthermore I wouldn't bother spending money on peat, coconut coir or anything else like that. I used to use shredded paper as bedding but I don't even bother with that anymore.

As has been mentioned by Brandi, shredded news paper (and any paper that uses soy or other vegetable ink (black only) will not harm the system), coconut coir is also good as are dead leaves.
The other biggie is moisture levels need to be fairly stable (I use a spray bottle to add moisture when needed) and over feeding is problematic so as has been mentioned, only add food when what is there is gone or nearly gone.
