I'd install the fixes yeah, Daggerfall can be a buggy/quirky game at the best of times. Personally I tend to skip the unofficial quest packs though.
Also, something to keep your eye on if you're interested in playing Daggerfall - there's a conversion/remake being done in Unity that's actually pretty far progressed now:http://www.dfworkshop.net/
You probably don't want to use it right now, but it may be worth keeping an eye on for its completion. They've been progressing pretty quick in recent months and, as of this week, the main quest of the game is now completable.
Here's the roadmap of what's done/what's left (the spell system is the biggest thing remaining here): http://www.dfworkshop.net/projects/daggerfall-unity/roadmap/
