Good to hear you are getting back in the saddle.
For general tuning and waxing basics, the Tools4Boards kits cover the basics well. Having said that using a nicer, dedicated SVST side edge beveler with a 200 & 400 grit diamond provides a nicer feel and quicker results. Add a panzer file and multi-angled guide for side wall cutting and scraper sharpening (a T4B Razor or Xact work great for these taskes as well as edge work). You can always add more stuff after you get more experience over time and start seeing gaps in your kit.
