Answer 1

Try this
((Repeater)e.Item.Parent).ID // this gives the ID as specified on the aspx page
If you need Unique ID, you have to use this
((Repeater)e.Item.Parent).ClientID

Answer 2

On Item command of Repeater you will have to first find the naming container of sender
it will return you datalist item.
then in returned list item you will have to find the repeater of that particular data list itme
once you will find the repeater you can easily find the controls of the item of repeater
