The v1.3 with the added U-Boat Missions Add-On does make the game equivalent to v1.5 Gold Edition, though it is better to have an all-in-one such as what Ubisoft offers. The newer download versions have recently changed their licensing, and that can make some of the old copy-paste techniques invalid for the game...
As for your mod list, make it like this:
4) Generic Mod Enabler - v2.6.0.157
[E:\Games\Silent Hunter Wolves of the Pacific\MODS]
100_FalloftheRisingSun_Ultimate_v1.8
101_FotRSUv18_FixPak.7z
Nippon_Maru_v1.9b_FotRSU
Nihon Kaigun v1.3a_FotRSU
Combined Roster
451a_TMOstyle_NavMapDots_Nippon_Maru
451b_TMOstyle_NavMapDots_Nihon_Kaigun
I'm not sure of what the "name" of the main mod is - I am not at my regular computer...
The "FI-OQ_FotRSU_v1.8f_upcPatch" is for if you use vickers03's
Fleetboat Interior: Officers Quarters mod. If you don't use vickers03's mod, you should not use the FI-OQ_FotRSU_v1.8f_upcPatch, but in your case, it would have been over-written by the main mod anyway, if you would have put that in... If you do want to do the interiors, then you would do

I am not familiar with the Full_Radio_FothRS mod, and cannot comment on it, but we (the FotRSU Team) recommend to not use any non-authorized mods. Do so at your own risk, but generally, so long as a given mod does not alter the Air, Library, Menu, Sea and Submarine files, you are usually OK to give it a go, and see what it does. The really big point (besides NOT using a Program Files folder) is to empty the old Save folder (C:\Users \UserName \Dcouments \SH4) to clear the old, pre-modded data. The game will re-create the folder, and populate it with the new settings of your mod list...
