Are there many classical and/or Biblical references in Don Quixote?

which question do you want answered?

Both or at least one of them if you please.

When Sancho gets his island, many references to Solomon-- he in fact basically BECOMES Solomon. First bit to come to mind. Samuel, Kings important perhaps.

This is correct. I'll assume most westerners have heard many of the famous tales of Solomon but if not, read what anon recommends. A little knowledge about chivalry and medieval stories helps, but you should be fine reading it. You can, and should, return and read it again after finishing the Bible and a lot of other studies though

There are relatively few classical references in Don Quixote. It mostly mocks earlier chivalric romances, which are really too boring to read, like Amadis de Gaule.

A better preparation for DQ would be reading the chivalric novels, but as the anon above said, they are mostly shit. Their tropes are parodied in DQ but let's be real you are probably familiar with all of them already. The classical/biblical references are rare and won't pose a problem.
Basically, just read it. Reading a chivalric novel might give a bit stronger context, but is certainly not necessary for a good reading experience. The novel rises above mere parody and is a great work by itself.
