First, welcome to the forum. You'll find a treasure trove of information here, plus a great bunch of helpful Rohrbaugh owners.
+1 on the Slide Glide. Brian Enos, the champion shooter / instructor markets this stuff on his website,
http://www.brianenos.com/. I've also seen it advertised lately in several of the mail order houses websites.
I'm sure the quality gun oil recommendation will work fine, but my R9S has been on a grease diet since new and I'm not about "to change what ain't broke". I don't butter up the parts too much, just a bit in the rails, in the muzzle end of the slide, the barrel locking lugs, and wherever I see evidence of contact.
For the fire controls, I bought a lifetime supply of Mobil 1 oil (a quart will last several lifetimes).
