What is the max number of volume "blocks" I should have so that I don't cause hearing damage? Does each block roughly correspond to 10dB of sound? Would using a higher resistance headphone make a difference(like a pair of 64ohms HD 280 pros) in the actual dB of sound. I cuurently listen at a max of 4 or 5 clicks of the volume rocker( or 5 "blocks"). Is this safe?

There are numerous studies online you can reference for the appropriate hearing levels. However, everyones hearing and hearing environment is different and these factors need to be accounted for. Hearing damage is an accumulated effect that you will need to monitor and then determine your daily safe level. The following links are few studies that you may find helpful in your search for a safe volume level.
I have also tried to find any reference to a "block", or "tick" of the volume level corresponding to 10 dB and have been unsuccessful. The dB level will depend on your iPod Touch, your headphones resistance, temperature, altitude (pressure) and other factors including age. A general rule of thumb is to keep the volume under 60% and listen less than four hours a day.
I personally work in a quiet environment and can easily hear my music with one click. Once I go for a run.... up to 50% it goes. Good luck.
