Most chemical reactions will increase in activity with an increase in 
temperature. If you use a warmer temperature for developing, the 
developement time will be shorter. For most developers, room temp (70-75 
degrees F) is within the range of proper use. Your goal of developing for
at 
least ten minutes is a good goal; shorter developer times will make any 
errors more critical. If your time is off by fifteen seconds and your
total 
developer time is three minutes, that's an im****tant error. If your total 
time is ten minutes, a fifteen second error is not so im****tant.

To find a developer that meets your needs, you may want to check out the 
massive developer chart at http://www.digitaltruth.com/devchart.html
.

(A water bath is a good practice for film developing. It can be as simple
as 
a large picnic cooler. Get one with the drain spout, it will make life 
easier.)
