mstechca,
You need to read up on some basic BJT theory before thinking of doing this properly. The 100mA spec. is one of the least characteristics you should be concerned with.
When designing an amplifier, you should only be concerned initially with what you have and what you need. This will give you a gain rating = output/input. Then you need to see if you need more then one stage in your amplifier.
You need to know what frequency you are amplifying, it is one of the most important specs. you should be worried about. Also, the source impedance would be nice to know or even have an approximation of.
Tell us exactly what you are trying to do.. example.. "I need to amplify a 50mVp-p wave at 90MHz to around 1Vp-p, I am using this as an FM amplifier. The source is a 75 Ohm antenna"
