Just starting

I am very new to tris and am in the beginning stages of training for several tris for 2009 (1st - International dis, 2nd - Xterra, 3rd - Sprint, 4th - IM Augusta 70.3).  I plan to follow the training plans shown on BT.  During the past month, I have been doing one of the three areas for a six day period with one full day off to build a base.  Occassionally, after a bike, I throw in a slow 1/2 mile run.  All of this is in a gym (pool, stationary bike (or spin class), and tm.  I am in there to build a base and work on form.  Once I feel comfortable (in a month or so), I will take everything (with the exception of the swim) outside.  While doing these, I am mostly looking at time as opposed to distances.  Am I starting the right way before I just right into the program?  I guess I am calling this my acclimation stage.  Thanks for your thoughts and suggestions.
