what are some good basic upgrades for the stock point 390? carb. , petronix?, headers? etc...

Headers are a great starting point on any motor.

Is petronix that kit to remove the points?

yea, i have headers on it, but they are the Full length Hookers and they make it so taht my i cant get to the plugs very easily. and yes the petronix replaces the points

My dad has one of those kits and it always needs to be adjusted or the car wont start. I thought the point in getting rid of points was so that you wouldn't need to be constantly adjusting things.

think its better to go with MSD ignition system then?

More expensive, but yes IMO. Performance wise I don't thik it makes a difference on a stock or close to stock motor.

What is your current set-up? Carb, cam, gears, etc?

600 cfm, prolly somewhere in the 2:90's range, stock cam, etc..

The 600 is fine for a stock set up. A mild build with a decent dual plane manifold can use up to a 750. Gears will really help, espicially with a posi. I have a CJ cam in mine that works well for me, I don't twist it too high. There are many other cam options out there as well as Aluminum heads. It depends on how far you want to go and how big your pocketbook is. FE's can be made to run good but it can get pricy.
