Advice on first basic upgades

[NovaJ]

Alright guys, first I want to apologize if this has been covered many times before, but if it has I couldn't find it.

Anyway, I wanted to do some things to my '72 nova over my Christmas break that would be a fairly simple install while still giving a somewhat noticeable improvement and maintain a pretty low budget. So I came up with this small list:
-DSE front service kit
-CPP disc brake kit (haven't decided on either front or all 4 wheel)
-DSE front sway bar

And then I might replace several of the bushings throughout the car as I am sure they could use a little attention also. My main concern was if getting the sway bar would help at all given that I would leave the coils, control arms, etc. all stock for now. My car currently has an inline 6, so I wanted to wait until I got around to the LS motor to start changing out more of the front suspension as I would imagine that will change how it handles and its stance.

Any and all input and/or advice is greatly appreciated.
Thanks
