Hi scrapser
firstly, this is the Modding section of SH3, any general enquiries about the game, or otherwise would need to be posted in here:
http://www.subsim.com/radioroom/forumdisplay.php?f=182
Now, as for your long 'lay-off',
i posted a thread with similar questions here:
http://www.subsim.com/radioroom/showthread.php?t=202321&page=3
which, i posted in the wrong section like you

but, it may give you some tips and tricks.
Also look here for a 'one-stop' go to place for all important must-have installs to accompany SH3 (and GWX3):

Hope that helps somewhat
