Answer

"Proof rather than argument"
論(ron)より証拠(shouko)

"If you believe everything you read, better not to read."
Is it really a Japanese proverb? I've never heard of it. Sorry. Wait other people's answers.

Answer

尽く書を信ずれば即ち書なきに如かず 
(Kotogotoku sho wo shinzureba sunawachi sho naki ni shikazu)

It's a classic Chinese quote from Mencius（孟子　Moushi）, rather than Japanese proverb. The credit should go to ancient China.
