What are the responsibilities of a parent?
Provide help and support for the troop and service unit. 
Work with your daughter on projects and activities.  Every girl will have a green folder that goes home. In the  folder are activities to continue what is being taught at the troop meetings.  Make sure that these are also completed with your daughter.
Attend troop meetings where awards are being presented to her. 
Attend and assist with troop outings. 
Attend campouts with your daughter. 

Who pays and gets the patches, books, uniforms?
Each troop handles this question as they may or may not have the funds to cover these items.  If they don't they might ask it to be part of the troop dues or ask that the parents go out and purchase these items on their own.  Our troop has decided to include these costs within the dues so that each parent isn't struggling with what to purchase and from where.

Is there a Girl Scout Magazine? If so, how much does it cost and how do I get a subscription?
No there is not.

How much is it going to cost? 
Each troop handles this question.  As a troop you could ask girls to bring a nominal fee each meeting for snacks &/or supplies or what we did was come up with the cost of each required item (uniform, books, necessary patches), then calculate how many fun patches you will work on, and of course supplies.  For a ballpark number since we had no idea, we said $30.

How often are the meetings? 
Each troop handles this question.  Our girls meet every other Monday, unless school is not in session.  Plus, there might be some weekend activities that we have set up, the council set up, or our service unit.

How do we handle expense reimbursement?
Each troop handles this question.  You might be required to turn in all receipts, copy/scan them, or fill out forms requesting reimbursement. 

What uniforms do Girl Scouts wear?
Each troop handles this question.  Each level has the different variations which could be vest, sash, or tunic.  Keep in mind a tunic will allow for more patch placements and allow for more growth of the girls.
