need a new alternator should i go with a stock or internal regulated type? how much more would it cost for the internal regulated alternator?

I would go with an internally regulated unit. I think most people would say the same. A typical internally regulated 63-Amp Alt usually runs around 50 bucks at most auto parts stores and the plug is usually around 5 bucks. It is really easy to do and I believe there is a write-up in the FAQ section.

Internally regulated by all means.

is it the same size as the one already on there? what about 1 wire alternators?

How did you determine that the alternator is bad? No charging, makes noise
what? They are pretty easy to fix if it's a bad bearing or brushes or a diode.
Here's a website that explains a lot about one wire alternators and also there are some threads posted just recently about leaving the idiot lite wire hooked up to excite the charging circuit in the alternator. I think it was started by Putter. The search feature isn't working yet or you could use that.
