1) let the custom maps finish the "loading" screen. most do that the first time you use them because the game in effect has to install them.

2) as far as the hud, open hobbs' hud mod in pakscape (search on http://www.google.com for "pakscape") and copy all the tga's with "compass" in the name to your desktop (they will be in the folder textures/hud inside the pk3) and then open the other hud mod and move the tga's into the same folder (textures/hud) inside that pk3. make sure you save it in pakscape (it will ask when your closing pakscape)

3) weapon skins are all force modeled regardless and I doubt there is a way to change that (anyone that knows of a way, feel free to proove me wrong here)

4) the view of your gun can be changed in options/advanced in moh, but, theres only a few different views available.

hope that helps a little.
