Potential new user looking for information.

I am currently using a borrowed flex 1500.  running the latest sdr software for it.  I want to use it for more than just hf.  I would like to use an amp if necessary, have transverters connected for vhf,uhf or satellite, and running digital modes.  I understand about the VAC software, but the amps and transverters are new to me.  Is there official documentation on these topics, are there suggested products I should be checking into. 

Thanks  KJ4TOP
