1/3 worm castings is a bit much. they tend to run a bit hot and could cause your soild to stay a little water-logged. 10-15 percent would probably be good.

bio bizz makes a great soil. the all mix has nutrients in it, and the light mix doesn't. just buy a quality potting soil and don't worry about mixing your own. sunshine #4 is good too.

you definitley should go to a 1 gallon then a 3. reason being is that you want the top and bottom of your plant to grow at close to the same rate. if you go straight from a jiffy cube/pot to a 3 gallon your roots will grow faster than the top of your plant and you will eventually become rootbound with a small upper half. a good rule of thumb is one gallon of pot space per foot of stem height.
