A few LDraw questions

[Dr. Brick]

I've just finished a MOC in Ldraw (MLCad or whatever) but I have a few questions that I've been wondering about for some time now:

1. How do I create a building manuel for a MOC I made?
   
2. How do I download new parts from LDraw.com (from the part list, but it never works)
   
3. How do I download a better viewing program like LDPub? (at the moment I'm using LDView)
   

Thanks everybody! :-)
