On ours the fridge was in the cockpit on the port side across from the helm. Don't remember the size, but I'd look at what NovaKool has to offer.
One of our Albins had a propane stovetop with the bottle stored just forward of the fridge in a compartment that was vented overboard.
Our other Albin had an Origo 3000 alcohol stove that worked quite handily for that size of vessel.
The propane stove was hotter but more complex; I'd be happy with either if I had an Albin again.
For a vent I'd look at Nicro. The solar powered ones look attractive but I've been cautioned that you need a lot of sunlight to make them work properly.
