What is the best all around gear ratio to use for a F350 7.3PSD 4x4?

Recently bought a 96 F350 PSD 4x4 with 4.10 gears and they seem way too short, so I would like to swap the gears for something a little lower. I thought about 3.55, but don't know what's the best way to go about doing it. I know some others have posted here about doing this swap, but I don't know how they came out.

I don't want to spend much $$ for the swap, and I'd like to exchange either gears, 3rd members, or entire axles with someone, if anyone is interested. If I have to buy parts, I would buy the gears from someone like Drivetrain Spec and install them myself, but I don't want to do that if I don't have to. Don't want junk yard parts, either.

What axles would this truck have? I've heard it should have a Dana in front and Ford in the rear. Does anyone know what axles they should be?
Also, I looked up geaaarsets for Dana and Ford, and one sells a 3.55 ratio and the other sells a 3.54 ratio, Is this OK? or do I need to make sure I get exactly the same ratio if I were to buy the gears?

Enough questions for now. Thanks for any help you guys can give. I'm new to this and can sure use some guidance.

 

dana 60 front, and sterling 10.25 rear.
