Small Issues with SPM 5 Do you have a fix?

Howdy, I have had the Alpha for a few months and really am trying to get my game to a playable state so that I can do a full game playthrough.

A couple of issues I have always encountered and am curious if anyone else has are:

1. Crashing in Dragonsreach. It seems no matter how many time I reinstall my game or mix up my load order I CTD trying to enter Dragonsreach.

Usually after reloading the game I can enter the building but may crash exiting, im not sure if this is due to a memory issue or how to fix this.

2. The Jarl of Riften's clothes dont have textures. Im not sure which file I need to replace but the female jarls clothes are a pasty grey blob with no textures,

Ive been trying to find fixes for these for months and cant track them down, anyone have suggestions??
