To foam or not to foam..that is the question..

Having used foam I'd say definitely yes for you to use foam for the following reasons:

1. It adds floatation - a very, very good thing in case of swamping etc right ?
2. It adds sound deadening - less hearing the water under the hull, sounds more solid.
3. You've already corrected problems, so it won't likely get soaked again.

Assuming you've used foam before, and know how to use it, you'll do a careful job to avoid the pitfalls:
1. Pouring too much in a section, then dealing with the expansion issues.
2. Avoid getting the liquild on your hull surfaces - almost nothing stains worse.
3. Mixing too much at a time.

Finally, it actually contributes to the boat's structural integrity, less flex, more firm overall when the foam is used correctly and expands to a nice tight fit into specific sections.
