about 5 or so years or so ago I made the same decision, after alot of research I went for a "ready to fly" RTF trainer the Nextar, and joined a local club, the 2 best things I did to start getting back in to the swing of things.

there is a listing at the top of the beginners page of many trainers all pretty good to start,I like powering my planes with fuel mainly because its where I started many years ago but there is alot of electric planes that fly good as well.

I dont know much about the radio you have, but for starters it sounds like it would serve you well for at least your first trainer,the radios that are available are unbelievable they do stuff that was not reachable when I first got into the hobby, but a basic 4channel radio will get you started for a trainer plane for sure.
a good size to start with is a 40 size trainer,and a 46 size engine.

the 40 size is big enough to be stable in most wind conditions,as well as being large enough to see at a safe altitude.
a 46 size engine my favorite being the OS46 for reliable running and ease of tuning,will give you years of performance, and also work in many planes you might want in the future,since getting back into RC I have found that WWII planes are my personal favorite, but there is so many cool ways to have fun in this hobby,just remember start with the basics and build from there.

I should add when I first started the only simulator was for scale pilots and NASA, the ones that are available are not only fun but are a huge training aid and have helped me learn so much faster than if I had to rely on actual stick time,the variety of planes to try is just endless.
I have a G-3.5 from great planes its a great sim there is alot of free downloads as well when you get the sim from www.knifeedge.com welcom back and have some fun.
