I think that Mike Long makes many good points, but remember you cannot add to or take away from the Scouting requirements. If you can the Scouting requirements you may have a group, but it is no longer Scouting, maybe Awanas or even Girl Scouts, but not Boy Scouts.
As for service project hours, Mike has already stated the service project hours are set forth in the Star and Life badges, Eagle however has no set requirement for hours. The Scout requirements provide that an individual create, plan and carry out a project, demonstrating service to the community and leadership. Generally a rule of thumb for our district is 40 hours, but that is not a requirement (see above). Then approval is received from the Scoutmaster (Scoutmaster's Conference), the Troop Committee (Committee Review) and the District Representative.
As for the leadership and attendance the Handbook requires leadership and your Scoutmaster can handle the attendance in his review. Remember your Scoutmaster is the main individual responsible for program. He is the one with the closest contact to the Scout and he is responsible for presnting the Scout at the Board of Review indicating his opinion that the Scout is ready for advancement.
Remember the Board of Review not only reviews the Scout but the effectiveness of the program. The Scoutmaster serves at the behest of the sponsoring organization and the committee. If the Scoutmaster is not doing the job, those groups are responsible for his/her removal.
