cjdelphi,
Get on-board and use the standard symbols. 
Anyway, what you're attempting to describe, with the output from the emitter is what's known as a power amplifier, common-collector configuration (or "emitter follower") - it's a pass transistor, the voltage regulator circuit depicted below.
The thing to bear in mind is that the difference between V_in and V_out is across the transistor, that's VCE. Your transistor's rated PD >> your output current * VCE.
