I don't know all the mods you have installed so far - but it looks ok to me
Install TDWs UI next and then OHII v1.3. Allow overwrites.

If Capthelms sound mod uses a sh.sdl - you will need to merge it with the one in OHII

Dont add imported ship pack as it is in OHII
You could also update TDWs FX to v0.19

I dont think you need the u-boat smoke mod. It is in TDW UI mod. (perhaps someone can confirm this)
