Eveyone else said it so i'll me a "me too": Get Trained. Its the first, best step.
You have young boys. So IMHO it would be best to help them learn to lead by showing/helping them. Also tell them that you want them to lead. Good place to start is to plan an overnighter. It involves all the leadership positions so everyone will get a chance to start doing their job. I would first meet with the adults and get them to buy into a mentoring role. Meaning they will help the boy so all goes well. But eventually the boys will be able to "do it all" themselves.
Being a new troop be careful not to judge yourselves too hard. There are a lot of troops out there that have been in existance for 50+ years, are rich in tradition and really "get the job done." In many ways you have a wonderful opportunity with a new troop. Your boys get to be "founding members", you get to make all your own traditions and you get to sow the seed that will grow into a healthy, active unit.
Whatever you do, don't give up. Its OK to get discouraged. I have quit scouting hundreds of times. The fact is we all need a break and its OK to take one. A day or two later I am always back at it. Planning the next outing, attending to advancement records or whatever.
Good luck! Hang in there.
