I've never heard of a Fresh Expressions licensing.
although, I will say, you might be best served to go in gently - Our lady priest that went to a new church had a traditional licensing, as dictated by the bishop, and the service was a blend of tradition and modern. She is happy-clappy, and the church in general is too, but she spent time when she moved there to question the parishioners on what they wanted.
Then she took everything on board in order to amalgamate.
That's when you put your own stamp on it.
Most people I know in churches say that a new incumbant should spend about a year (so they can see everything that happens in the church) watching and learning.
Then if things need to change, you introduce it gently "ooh, let's see if such and such would work. Let's try it for somany months. If it doesn't work, we can re-think"
I'm sure you know all this, because you said "but more going in and praying, worshipping, staking the ground so to speak ", so it looks like you're not going to "do a Nick" (which is what our last vicar did - "hello, I know you've got a long tradition here at St Michael's but i hate tradition, so what I'm going to do is rip out all the furniture, change everything, reduce the congregation to the bare bones and talk down to everyone that has put in years of hard work into this church. Oh, while we're here, let's also get rid of the organ and the robed choir, put in stupid screens and.... oh, where did everyone go? 
" )
Best thing for your induction is probably just to ask for the music you want, and let the church do the rest. :)
