Tepedelen, welcome to the forums.
First general rule of thumb: do a search on each of your questions in the V:TM forum database. You'll find a lot of your requests for opinions and facts are answered there--in spades. Try that for character building ideas, as well a few other points you raise.
If you still have specific questions after doing searches on the above, and nothing has helped, feel free to start threads with specific questions.
