More in without the ability to get more out =0, You would also need to add tune, heads, injectors, headers & exhaust.

Most add headers and exhaust first as they are simple upgrades they will give you a true 20hp+ gain. Another bang for the buck are rear gears they will not add HP but a seat of the pants gain at the low end. After that its all dependent on your $$$$$.

The exhaust system is the first place most owners go, but that is really just the first step. The exhaust (headers, pipes) won't give you any real power increase (by themselves), but freeing up the exhaust enables the next steps (cam, heads, etc.) to do the job they can do. Adding horsepower is a system, with the total greater than the sum of its parts.
It's a series of building blocks, each mod building on the ones before it AND the ones after it.
Aftermarket power: figure on spending about $50 total for every one horsepower you increase. Want another 100hp? Plan on writing a $5000 check.
(this includes professional installation and/or replacing broken parts, in the case of nitrous)

I do agree with almost everything you say but whats in red, although not an LT1 headers and freeflowing exhaust/with cats added 20+ rwhp to mine. I started with 324rwhp and went to 349rwhp.

I've found this to be about the most comprehensive and straight forward info on the topic of the LT1.
In the years that I have been on here, the one thing I have read is that the stock TB can handle just about anything you throw at it until you start adding cubic inches to the cylinders, even then it depends on your cam and heads.
What folks seem to agree on for the LT1 is long tube headers, 1.6 rockers and springs, and rear end gears. These seem to give the most bang for buck without cracking open the engine.

The hypertech is good for altering speedo calibration if you change the rear gears, changing shift points in auto trans and I think the rev limiter in your year. On a '96 you can change the fans turn on and off temps - IDK if you can do that on yours. Otherwise, to my knowledge, you won't get any more engine power from it.
