The tech section of this site, as well as Ibanezrules are both excellent in taking off the training wheels for your own set-ups. It's well worth the effort. Might be worth doing on a cheaper guitar until you're comfortable with your own skills.
Dan Erlewine has some excellent books which are deep dives into guitar set-up/repair. The latest revision has him working on a RG570.
In the meantime, having a good tech/luthier you can take your guitar to is your best bet.
Personally, I hate setting intonation, so I'll pay every few years. Especially if you don't have an intonation adjustment tool.
I recently switched back to 9's as I found 8's to be a little too sensitive. Fret a chord a little heavy and it sounded off. I always played 8's because they were easier to bend. But the switch back to 9's was well worth it, and my increased finger strength made up the difference in no time.
