Welcome aboard sir! I would say GWX is a good pick too. If you need it, I got it uploaded on my FileFront,
you'll need
GWX.exe
GWX-1.bin
GWX-2.bin
GWX-3.bin
GWX-4.bin
GWX-5.bin
All of them need to be in a folder together and you got to have a clean unmodded SH3 patched to 1.4 and then all you gotta do is double click your GWX.exe and away you go. Then get GWX103.exe to bring the installation of GWX up to date.
All GWX material is in my sig there where the link is in bold. There are others round here who have GWX uploaded besides myself.
Be sure to try some of the other mods on offer too, and practicing with SH3 unmodded before hand, is an excellent idea. So you get used to things.
