Help needed!

Right now I know virtually nothing about the whole world of synth guitar. I understand the basic principles and I've seen videos of what a properly set-up synth guitar can do, but I have some questions about what I'm trying to achieve.

My custom 8 is going to have a Hipshot bridge- Graphtech makes Ghost saddles that will fit in this, right? If not, do I have any other options? Does Graphtech sell individual saddles so I don't have an extra 4 lying around?

All I really want to be able to do is trigger a few decent synth patches for instruments like piano and strings (as well as maybe a few weird noisy ones) and I really want to be able to run these sounds through my guitar head. Or at least have the sound come out of the cab, able to be blended with the magnetic pickups' tone. Is this typically easy, or do people generally use two different amps if they don't have the option of running through a PA?

What are my options for converters and synth modules? I know Roland is toted around pretty much exclusively, but are they the only ones making these kinds of products? Again I don't kneed the most complicated modules, just some good instrument sounds and I'm happy.

Thanks in advance for educating a complete newbie on the topic
