The reading error your getting is because of the scratches on the original, you could try using bling read to get round this but you wont be able to get a "perfect copy" because blindread will insert zero's where it cant read information from the PSX original and no PSX contains zero's. You would be better off backing up from a disc that that give no reading errors with CDRWin.

The settings for CDRWin should all be left as default and make sure that the RAW box is also #####ed. You may want to reduce your read speed to 4x and your write speed to 2x for best results.

As far as the internal mod chip is concerned then i cant realy advise of a trusted site to buy one as i program and install my own, but with the PSX 1 you must have a chip that contains the MM3 (Multi Mode version 3) hex unless this has since been superceeded!

You could try www.paulmax.eng.net as they have always had trusted code and diagrams and i would presume that their customer support would be the same.
