Tune up time for a 440 375 HP, opinions needed

[XXXGoldL34M20]

My car is running crappy.
Called the last owner and he told me it was 7 years since the Distributor cap/Rotor and Points were touched so i ordered a Pertronix kit, New Distributor Cap and fresh Spark Plugs.

I took the distributor out today and i was wondering what all these numbers mean (See Photos)
Also have a look at the photo with the Advance springs, there are 2 different ones and the thicker orange one seems to be stretched out.
Should i order new Advance springs as well?

Was thinking of getting the Mopar P2932675 springs, what do you guys think??
The P2932675 are designed to convert a stock distributor to a quick advance curve in order to optimize the ignition timing. So would this work better than the stock springs i have now to run with the pertronix?

Also help decoding the parts would be much appreciated




, Thank You
