Can anyone here help with Pathfinder?

I have two character concepts, but I don't know how to create either character in Pathfinder. I have the core rulebook, but not with me, so I have been trying to use the system reference guide.

At this point I think:

1. The character classes are way way way too restrictive. The game either needs new classes to cover the gaps or it needs to rewrite the classes so there's some flexibility.

2. The system reference guide is horribly disorganized and is misleading when creating a character, because earlier steps often depend on later steps.
