I just got some boots, loving the feeling, the whiplash will get better soon!
I had all the same fears as yourself, as for putting the boots on get down the chemist and buy some water based lube, don't explain just smile and if she's hot give her a wink.
The one thing I have noticed is don't bury the nose at all, the bindings turn your board into a submarine (WHIPLASH).
Other than that i find you can ride harder, faster and smoother (if you use lube)
