For the gurgles, let the tobacco dry out a little more before you pack. Smoke slower.
For the cake, just smoke. It'll grow, don't worry. It will take time. I'm still a n00b in every since for the most part, and just now getting some decent cake on my favorite pipe. Most of the others, not really. Best thing to do is not even worry about it, and it'll be there before you even know it.
Now, reading on here, i've seen that burley tobaccos do form cake faster, but only smoke the same tobaccos in the same pipe (ie aromatics in one pipe, englishes in another, etc). With burley though in my experience, I get more goop than anything else in the pipe.
PS, check out the sticky and you'll probably find a lot more information there.
