Help: need 1995 Caprice Classic tune-up advice

Hi folks
I just had the fuel pump replaced in my '95 Caprice Classic that has the 4.3 L V8 and 72 k on it. (The engine wouldn't even turn over and obviously wasn't getting any gas.) After the fuel pump was replaced, I'm still getting some loading up/hesitation and even a stall once in a while when it is cold or has been run mostly in town.
I am the third owner and I'm pretty sure the car has never been tuned. My youngest boy and I love the car, but I've put a ton of money in it in the last year (alternator, AC compressor, suspension etc.). So does anyone know of a good basic tune-up combination of parts (distributor cap, plug wires, plugs) that would help performance but not cost an arm and a leg? My mechanic says the replacement caps are expensive for that engine.
Any help or advice is most appreciated.

Put in new AC spark plugs. Ohm each wire for continuity as you do the plugs.
If bad it is usually within 2 or 3 inchs of the plug. If you have a tool you can repair. Inspect the rotor and distributor cap. Replace any bad parts.
Spray around the intake manifold and if it smooths out fix the vacuum leak.

I use carb cleaner it will mask a leaking intake. This lets you know you have a leak.

change your in-line fuel filter. it is recommended at least once every other year and will cause hesitation- very cheap and easy to do 10- 15minutes max and maybe $10

also if that doesnt cure the hesitation next i would change the coil. but the filter should do it i had the same problem when i took off my filter it was so clogged i could hardly blow through it (poor fuel pump was working very hard...also the reason why they fail early)
