I made getting dropped on climbs an art form. What eventually helped me was to start the climb in the front of the group and hopefully, as I slid to the back, the climb ended before being dropped.
This is a time honored tactic for us non-climbers.
As far as training goes, hill repeats is the way to go. You don't need any equipment other than a stopwatch or timing function on your computer. Set a benchmark time, and then set out to beat it. Rinse and repeat.
