My advice is to contact your demonstrator and ask for a recruit packet to look over, explaining you are unsure, and not ready to commit, but really would like the info.
You are not obligated to sign up at all, nor under any particular demo'r, including the one you requested the materials from, however, out of courtesy, you should return the materials to her, if you don't sign up or choose to sign up under someone else.
Some prefer local demo'rs for uplines, and others are fine with long-distance.
Every recruiter is at liberty to offer whatever she deems works for her as an incentive for signing and for training purposes, and it varies vastly from demo'r to demo'r. Determine what it is you expect or wish for from an upline and be sure to find out if they will be the type you can work with before you commit.
The answers to your questions above will receive a myriad of answers as vast as the # of demo'rs within the company. There are over 30,000, each with different experiences, different motivations/goals, etc.
Good luck in your decision.
