Welcome back!
You'll need Stock SHIII + Patch 1.4b (from:

There's new versions of JSGME and SH3 Commander available as well. JSGME ships with GWX and has an automatic update button on it, I can't remember exactly where I found SH3 Commander, but you can search for it.
2.1 is the latest version of GWX.
