My Quandry..help...please

Do you remember me saying in my "all about me" section that i am a relatively new chorister? Well, let me clarify...I am a brand new chorister. I've only had this calling since November which means i barely know what's going on most days. (i guess maybe i'm a slow learner??) It's been almost 16 years since i last served in primary and while I LOVE being back in primary, i am at a loss most sundays concerning the order and functionality of things. I am in awe at all of you who enter the primary room with confidence on sundays (or at least look like you are confident). So you're wondering what's my point? Well, this is my quandry...how much time do i spend teaching doctrine versus singing with the children on sundays? I have pored over other chorister blogs, lds.org, Pat Graham's songbook companion and anything else i can find and this is what i've found: everyone does it different. Maybe that's my answer then?? I guess I just need to find my way and go with it, right? I just want to sing sing sing each week but then i wonder if i should be teaching more?? But isn't that what sharing time's for?? i'm not sure but i do know that my 20 min. (which more often that not is 10 or 15 min.) disappears so quickly and i barely have time for singing much less teaching. With that in mind, i wanted input from all of you seasoned or otherwise experienced choristers. How do you find the balance? Do you have any advice for me?
