In addition to the first 10 amendments in the bill of rights, were there other amendments that were being seriously considered at the time, but did not make it into law?

Yes. The 1st Congress sent twelve amendments to the states for ratification, and the ten they ratified became the Bill of Rights.

The second proposed amendment was ratified in 1992 and became the 27th Amendment, which dictates that any change made to the pay of Congress goes into effect in the subsequent Congress (not the current one).

The first proposed amendment still hasn't been ratified. It's called the Congressional Apportionment Amendment and it has to do with the size of the House of Representatives as the country expanded in size and population. Had it been ratified, it would essentially say that the House can have no less than 200 representatives and no more than one for every 50,000 people (which today would mean the House could have no more than around 6500 members). It came one vote short of taking effect on several occasions, but no state has ratified it since 1792.

You'll find this in Jack Labunski's James Madison and the Struggle for the Bill of Rights.

This article talks about the passage of the 27th Amendment.
