A pro set up certainly its very useful, and depending on the stock action the bass was set up with. It could be extremely useful, or potentially a waste.
The first thing I’d do is watch and try and play through all of Josh’s free videos on YouTube. Then if your enjoying it, buy the full program. (You can send that commission check anytime @JoshFossgreen) 
But for real, the program is fantastic.
In regards to amplification, many directions you can go here. You could go with a traditional combo practice amp setting you back $50-$100. It would allow you to play to through the speaker, or you could plug in headphones, but you would be restricted to wherever the amp is. At this price point amps are pretty light but none the less something to consider. Your other major option is to get a pocket amplifier. It would allow you to play anywhere, but only through headphones. It is a down side but I will tell you this is personally how I work through the program and love it. Heres a link to another thread on this site that better explains exactly how I do it.
