just to throw something else into the pot...
If you change the sprocket no. of teeth, and go for a bigger chain (more links), then you really should have the ride height re-set too.
Again, ask an expert (not me!) about this.
If you go for a quick-release sprocket carrier (I did), then one of the benefits is that when you want to change sprockets in the future, it's a dead simple job (10 mins) to DIY. No need to call in the "experts"!
