Marriage Information Not Easy to Read--Help

I found a marriage record for Salvador Trillo who I'm sure is Salvador Tello. Can anyone please help me figure out a few important facts I need to find? This record is written with many abbreviated words and possibly has Latin words also. Anyway, can anyone please tell me if you can find out this information for me:

1. Does it state Salvador's age and his parents ethnic identity
2. Does it state his wife's age and her parents ethnic identity
3. I see the word esclavo, does that mean he may have been a chained property?
4. Does it mention his master's name.
5. Is anyone willing to translate the complete document for me?

Can you tell me where else on this records I can look to find more information on Salvador and his wife Juana Maria Aguilar. I have researched every record in Zacatecas and have not found children born tho this couple in Zacatecas.
