To answer your last question first. the fuses should be closest to the batteries.
In a parallel bank only one fuse is required, on the positive feed wire to loads.
On the wire going from the positive bus of the house bank to the Perko switch the fuse should be larger - ANL preferred. Alternator output fuse should be an ANL as well. Or MRBF fuses on the bus for each.
The rest looks pretty good.
