Welcome back old salt! Both of these threads are in the "Stickie" section up above:
THEBERBSTER's "SH4 <> TUTORIALS <> HOW TO DO IT <> INFO <> DOWNLOAD LINKS -STICKY INDEX"
... and ...
Rockin Robbins' "Sub Skipper's Bag of Tricks"
Both, treasure troves of knowledge and enlightenment...
In the meantime,
TMO 2.5 (and patch) is still in use, as is
RSRDC (and patch)
TMO also still has Dave Grayson's training wheels (available with paid subscription)
If you like TMO / RSRDC withOTC, then you can't go wrong with Bleiente's
Ralles Real Mod Soup mix of them
THEBERBSTER recently took Webster's Game Fixes Only mod, and added his own touch to it with
THEBERBSTEES All In One Beginners Mega Mod List For SH4 221117
And for the AOTD_MadMax team fans' favorite of FotRS, there is now
Fall of the Rising Sun Ultimate Edition, with 'beta' v0.72 on the back burner simmering as we speak.
There are others, but it's kinda tough making links on this tablet...
