Mac OS X: delete key??

delete key??

hello its me again!!

sorry still getting used to the Mac.

in the windows PC laptops there was a 'delete' and backspace key. I realized that the MBP has 'delete' key = backspace key (PC).

Is there a delete key on the MBP's keyboard,
so a windows delete= MBP's ??? Some key that deletes from front (hope i am not confusing you all!!)

Also, i noticed that there are 2 'enter' keys ..one at usual place and one next to the right hand side 'apple' key. What is the purpose of the bottom near apple ,enter key ??

i promise i will buy the mac os x for dummies book,pretty soon!!

thanks
