Changing rings, cassette and chain

Hi, i am looking for changing those parts and need help with their compatibility or maybe suggest other parts.
details here on my bike: http://www.bikeforums.net/classic-vi...l#post19451331
curently its running on campagnolo cassette 7 speed 12-25 with rear derailleur 7 speed veloce i guess, and 2x speed front derailleur veloce, front chainrings and 53/39 campagnolo 10xspeed engraved and sram pc 50 chain.
when the chain fell,skipped during a climb i hit the ground so i decided to change all.
my question is if these are also compatible?
Imgur: The most awesome images on the Internet
or maybe you find or know other websites that sell campagnolo chainrings and cassette for the same ammount price range , the chain rings should be between 52-53, 34-36, cassette 11-28, 11-32, and chain what would be compatible.preferably silver do not want to change crank too (campagnolo record 172.5).
thx for your help

Only thing I can guess , is the chainrings are likely a 135 bolt circle, other than <C>,

there are after market chainrings made to go in place of what is their unique bolt pattern.

Can't help with internet shopping..

There are likely less-drastic fixes for a dropped chain than a full drivetrain replacement. A simple limit adjustment or shifting technique change (don't shift under load) may be all that is required.

Be sure about that. Chainrings wear at a much slower rate than chains and cassettes/freewheels. Good quality chainrings last tens of thousands of miles. 90% of the time, chain slip occurs because of either worn chains or worn rear cogs. Start with those parts before you draw conclusions about your chainrings

chain fell from big ring on small one , and its a bit oval + not straight. no matter how well front derailleur is tooned 1/8 side will scratch the cage of the derailleur at certain ratios but not all.they all have 15.3k km at least from my use so probably even more.So kinda want to change them all and maybe change ratios too .

Just to be sure it's clear; no those shimano chainrigs will not fit that campy crank.
Can't see what the sunrace cassette fits, but you need campy fit for campy hub.
Can you shop on ebay where you live? Might do well there.
I don't know who sells the parts you need for the prices you want, cool bike though.
I buy lots of used parts on ebay and do well even with a few not so good purchases.
