MGSO and other mods +question about faction mods

[Sorenant]

I read the credits/mod list of MGSO and looks like there is no mods that changes the gameplay itself but I want to be sure that mods like these listed below won't conflict with it.

Galsiah's Character Development;
Animal realism;
Races are more fun;
Birthsign mod(not sure which should I take...); and
Wakim's Game Improvements.

I got too used to mod with tools that makes it easy like Nexus Mod Manager that I'm bit afraid to handle it on Morrowind, that have nothing like this (Though Wrye Mash seems to be something like NMM I didn't installed Morrowind yet to give it a proper look).

Thank you Scozzar for the helpful and fast reply!

Sorry for the double post but since I want to ask a new question, bumping this thread seems to be a better option than creating a entire new thread.

My question is:

1)Is there any mods that expands Morag Tong, giving it more missions? I did some research and only found changes like new room, armor replacement et cetera;

2)I got the House Dagoth mod by The Mad God and want to know what exactly this mod do. The readme just says how you join it and the Sleepers will treat you after joining them but nothing about missions or something. Is it like "join the House Dagoth and live in this doomed world"?
