Practical study for a former player? I played quite often in the mid 80's to mid 90's. My highest rating OTB was low 1300's (Edited, I had thought I reached 1415, but not according to USCF site-although that doesn't include my high school stuff in the 80's) under the USCF, with somewhat desultory study habits, although I did do a lot of reading on general tactics, pawn structures and some theory. Two best results were a round upset prize at the Western Open, and a $3000 check in the U1300 at the tournament in Vegas in December (Forgot the name).

I have been getting interested in playing again, and started looking at what is out there, and I'm a bit overwhelmed with the tools that are available now.

Where should I start? I'm probably way beyond most "pawns move one or two squares" beginner books, but probably not up to speed on even intermediate books, I vaguely remember bits of a couple openings, etc.

And, what openings should I concentrate on learning first, that will allow me to expand? IIRC, I played Scotch, French and was toying with the Indian openings.

I tried to phrase this so as not to encourage open ended debate, and I don't think it quite fits the suggested questions already existing. If it still is deemed too broad, make a couple suggestions and I can edit for fit.
I am going to make a few suggestions on reading material.

Pay a visit to Dan Heisman's column at Chess Cafe called the Novice Nook. Pay special attention to what he writes on the topic of Real Chess (article 1 and article two).

Focus as much as you can on this "Real Chess" idea in your studies and games. Always remember you will play the way you train. Therefore put a lot of training into proper over-the-board analysis. A book like Practical Chess Exercises can be useful for this as it has a mixture of tactical and positional positions so you are never certain if you should be looking for a forced sequence or a positional idea.

Honestly I would not spend a ton of time studying the openings. But software like Chess Position Trainer can help you a lot. As far as which ones, stick with the ones you enjoyed in the past and learn new ones that you see in your studies.

For literature I think Ludek Pachman's Modern Chess Strategy is probably one of the first books you should read. I also really like Silman's Complete Endgame Course: From Beginner To Master for fundamental endgame theory that is highly practical.
