Discarding cards to power theif ability

[Danyon]

Hi, I have 2 questions regarding what cards you can discard when using a thief's theft ability.

1. Can you discard an item enhancer from a item to theft?

2. If you discard a cheat card that has an item attached to theft, does the item on the cheat card go with it or do you get to keep it?

Thanks in advance
