As far as #2, I got married in Bogota and had to have some things notorized and apostilled but I don't remember having anything translated except my birth certificate.
I also had to have 2 notarized statements from friends saying I was able to marry.
It might be best to contact a notary in Colombia that will do the service and ask what they require.Here is a helpful website also:http://bogota.usembassy.gov/marriage.html
