Again:
- The pins are ONLY there to keep the cassette together when handled OFF the bike
- ON the bike, ALL the driving torque is handled by the SPLINES on the FREEHUB body and the TABS on each sprocket.
The pins bent because SOMETHING ELSE went wrong FIRST.
Something with the spline /tab interface between body and sprockets.
You need to figure out WHAT before you're able to tell what - if anything - to improve.
Otherwise, you're simply replacing parts and spending time and money randomly.

So unless you LIKE random shopping, why not WAIT with buying stuff until you UNDERSTAND what they do?

There really isn't much "fun" that can be done to a cassette.
The big thing about them is which tooth counts they contain.
Two cassettes with the same tooth counts will be (very close to) functionally identical.
They all work very much the same. You can get them lighter and you can get them shinier, but that's about it.
No one but you will ever realize, or care, that you're using a "custom" cassette.

But that's the thing. You CAN'T make a cassette that's overall better in any important way.
That's like trying to make better lug nuts for a car. Or a better radiator cap.
You can tweak the ratios to make it more suited to your riding, but that's better FOR YOU, not overall better.
You can get them a little lighter, and you can get them shinier. That's it. End of story.
You CAN'T get them stronger, because no one needs them stronger. Your failure was NOT caused by weak parts.

So you have:
a triple front
7-speed rear
dream of an 8-32 cassette
and want to go to a double front
Are you sure you understand what that would mean for the rideability of the bike?
(if it had been possible to build such a thing)
Unless you kept the 32 as a bailout gear that's considerably bigger than the others, you'd get very big steps between the gears.
Pretty much the opposite of what people normally want for good rideability.
For a nicer riding bike, keep the triple.
Use the middle and even the small more.
(or possibly replace the middle ring with a smaller one)
Get a tighter spaced cassette.
You DON'T need to go below 11T.
Your bike will ALREADY allow an average rider to stay on power past 30 mph.
If you're regularly faster than that on the flat, you deserve a better bike.
If you can keep it up for more than a few seconds, you deserve a sponsorship.

You do that. Ride more. Do some homework on how bikes and bike riding actually work. And what happens when you change this or that.

For 7-speed, I don't think so. That age is long since past. Not unless you buy cassettes and disassemble them.
For newer stuff, you can still buy individual sprockets:
Comparatif Miche Sprockets & Parts on sale at XXcycle - en
or here:
Mel Pinto Imports
Or maybe here:
Cassettes & Sprockets
Or why not get one of these:
http://www.miche.it/products/compone...y-pignoni.html
and tinker away to your heart's content.
You'll have to assemble it yourself.
Doesn't even come with pins.
And expect it to cost several times the value of your bike.
for little to no riding benefit.
