Any brand of kit for your model of transmission will work. No matter what the brand name on the packaging the parts inside the kit come from only a couple of manufacteurs.
OEM friction plates are Raybestos plates. Gasket sets typically from only a couple of companies.
Don't get caught up in B & M etc. These companies just repackage stock stuff. You often end up paying more only for the name.
Do a complete rebuild: ie frictions, steels, bushings, both bands, washers, filter etc.
Converter wise, unless you have increased the horsepower and torque, a stock converter will suit you just fine for a street vehicle.
Now, if you're going racing there are a ton of other options for you.
