I very recently finished P4G and I didn't use any guide on what to do. The game isn't strict on what you do in your free time, and until you reach the last 20-30 hours,almost nothing you do matters for the ending you get (one or two S.Links matter, besides that, it's mostly a series of choices near the end). As for which S. Links to pursue, just hang out with people you like. They just grant bonus XP (and occasionally a skill or two or perks to party members such as helping a downed ally back up). P4G's all about living the life you want, don't fret over it. You'll have ample time.
Basically this. P4G gives you all the time in the world to do everything you want to. You only really have to follow a set schedule if you're going for 100%, which you should most definitely not try on a first playthrough.
