If I need to spread my 4 point weight across a given area. How would I "Caluculate" and select the correct plate thickness, ie 3/8in, 1/2in, etc. Let's assume 5000LBS -
Dimensions - 5ft (60in) x 5ft(60in) x 4ft(48in)
See there a website or table in a book

It would help to know what deflection can be tolerated, actually it is critical to know, deflection will probably be far more important than, say, shear strength . What does "point" mean in this context. The dimensions given don't really explain much.
Even with the limited information, if I had 3/8' or 1/2" plate on hand, I'd probably just use it and not lose any sleep over it. If all I had was 1/8", I'd probably think seriously about doing some calculations, or, more likely, 'cause I'm lazy, just buy some thicker plate.

Get your hands on a AISC Steel Construction Manual - Allowable Stress Design.
It has a very detailed procedure for designing steel baseplates, depending on what the steel plate is bearing on (i.e. concrete?) and how the load is transmitted into the baseplate from the loaded column..
