It should be compatible unless the mod is purely made for minecraft 1.7.2
Use minecraft forge or modloader so that the mods are compatible.
This is a question to ask on the My Minecraft Mods forum topic. It may not be compatible with a Mac yet.
Check the forums for your other mods to see what mods they are compatible with.
Search Yahoo/Google/Bing for "Minecraft Mods". Read the instructions on what and how to install them and see if they are compatible with the other mods your going to put in.
Yes.
You wouldn't be allowed to this because of copyright. The minecraft copyright states "Do not distribute". So making a minecraft.jar file with those mods installed would be breaking the copyright.
The mod developer will need to update the mod to be compatible with the new Minecraft version.
