Welcome to the forum and the addiction. CLP is fine. Find a lube you like, or you can wait and watch this thread fill will everyone's favorite brand they like to help you choose. I use M-Pro7 cleaner and lube.
Yes, many opinions. CLP is good Rem Oil not the best compared to todays modern lubricants. My personal go to lube is Gun Butter both oil and grease. Reminder that your 15-22 does not require very much lubricant.
