Welcome! Yeah, reading through this site in general and through many of the over 35 logs can light a fire.
Since you're a former athlete you probably have a pretty decent understanding of some simple workouts you can begin with to get back into it. what's important is that you begin, get in the gym and start moving some weight, do some cardio, and then come back in here and log your workouts. You'll find many knowledgeable lifters in this forum provide encouragement and friendly advise on technique and workout routines.
Specifically, what are you your training goals?
Good luck, and I look forward to following your progress.
