The only advice I can give on boats is to climb around in them and see how you like the storage and layout. I saw a Vexus up close at the ramp the other day, and man it was sharp! The type of water you fish and species you're after make a big difference as well.
As for electronics, a pair of 9/10" Garmins with Livescope. You can go bigger on the screens but I think you reach the point of diminishing returns pretty quickly price wise when a 9" is $699 and a 12" is $1499.
