A TH350 convertor will fit a TH400. Gives you a little higher stall, and way less cash than an aftermarket convertor. Problem is you never really know how much more stall you'll get. (it won't be less!)
Most 350 convertors have been rebuilt so many times by who knows how many people you never really know if they went in and replaced all the parts or just built one out of spare parts. And did they tweak all the vanes to spec or slap them together? But that's also pretty true of most aftermarket convertors too.
A cooler is never a bad idea- for anything that is going to get used hard. GM added them on trucks that were going to be towing.

If you are going to buy a converter, call the converter techs and let them spec one for you. Why would you get advice from folks who know nothing about your car? The techs will ask you all the right questions, take the data they need, and come back with the right converter for your engine/tranny and your driving habits. Just pick a good name brand [for God's sake, don't buy a converter at a local auto parts store 
], and let them do the work.

Converter
Make sure you know what your existing converter bolt pattern is. Not all TH350 and TH400 converters are interchangeable. GM used two different bolt patterns, 10.75" and 11.50", so it is dependent on what flywheel you have.

help
this is true, but I like to be able to know a little before I call, and was wondering who to call. I know nothing and have no experience when it comes to TQ conv. This is always a good place for advice and a general direction, yourself included.... thanks for the help.

I told Andre I wanted to go through the traps at 7500 rpms at 180 mph. Data logger says finish line rpms are between 7496 and less than 7600. He hit it right on the head, first try.
His street converters are less money than his race versions like mine.
