How do I know which is the primary and secondary IDE Bus? Is the secondary the 40 wire cable and primary is the 80 wire cable?

Usually the IDE connectors on the motherboard will be labeled IDE 0 and IDE 1, or IDE 1 and IDE 2.

Your computer's boot HD will be in the Primary IDE cable.

40 is older and for low data rates.
80 is still 40, but needs 80 for faster data rates. - Skin effect, capactive loading, I dont know but thats how they do it now.
Look for IDE0 on the Silkscreen.
