If it's at speed, probably not. The splashing is likely coming off the leading edge of the LU. That's not an area covered by the foil (the foil does a couple of things, as I understand it: isolates air and prop for less aeration, and redirects upward water flow back down, which is where the lift comes from. It's not acting as a wing, as far as I know.)
Reducing splashing generally means raising the motor on the transom, as long as it doesn't cause aeration (usually in tight turns.) Some people who can't raise the motor have fitted panels to block spray from coming over the transom.

I also manage to break off a grease nipple. Are they replaceable? Can I get a generic one or are they specific to make/brand?

I assume they come in 2 flavors, Imperial and metric, though I have no evidence to back that up. They are simply threaded in in most cases. Should be able to find some at a local auto parts place, and as I recall they're cheap enough that if they don't fit, it won't hurt much.

Lastly there's a sticker that says my motor has to be bolted to the transom. Is this necessary/required? If so, do I bolt it straight through the transom?

Probably not, but make sure any clamp screws are *very* secure. Many people also tether the motor to the boat with a stainless cable just in case the motor decides to jump ship.
If you do decide to bolt it, drill through slightly oversize, epoxy line (or glass, or otherwise seal) the bored holes to seal them up, and use caulk or PU sealant on the nuts and bolts at the inner and outer joins. Transom rot is not an easy fix.
