Whopity makes a good point. This isn't difficult. Norwich isn't busy airspace and the controllers are very helpful - but they won't be happy if you don't know what you are doing. And rightly so.
The absolute essentials are to know what your initial call should be, and to read back the stuff you need to read back, properly. And do what they tell you to do once you are inside controlled airspace!
But I think others have covered these points pretty well, so overall I'd say just go and do it. Your experience at Gloucester won't be far off the mark.
