Ok I'm back again (I know, you're getting sick of me :P). But I've just play tested your mod and I've run into a few problems.
First off, I have my own mod installed, but none of the files I've modded are the same as the ones you've modded, so I didn't try to merge the two mods and I've activated both. They seem to be working without conflict (but I could be wrong, it's been known to happen :P).
Ok, firt problem (very minor) at the Character Creation screen, the character wasn't centered on the screen, when I tried to customise her appearance she was hidden behind the window and I couldn't see the changes I was making (this may have something to do with my monitor resolution though).
2nd problem, there was no dialogue at all. When I played solo before (by leaving my companion behind on the beach) my character 'spoke to herself'. Things like 'If I didn't know better, I'd think this was a peaceful beach' and 'What's that corpse doing here alone?' this time there was none of that, just silence.
When I read the journal from the corpse, my jornal updated and an exclamation mark appeared over my character's head, but again, my character didn't say anything.
Next problem, the shell on the beach was silent, no 'Oh mighty ocean, how I pine for thee..' and I couldn't interact with him at all.
The same thing happened with the guards at the bridge, they wouldn't talk to me and I couldn't talk to them.
The battle with the orcs on the beach went as planned, but afterwards, even though Arhu opened the gate, he wouldn't talk to me either

That's as far as I got. I decided to stop there.
Could the two mods be conflicting with each other after all?
