I read the standard transaction fee info at  https://en.bitcoin.it/wiki/Transaction_fees

But I still have a few questions:
•   What happens if you do not send the full standard .0005 BTC transaction fee?  How long is the confirmation typically delayed?
•   What happens if you send no transaction fee? How long is the confirmation typically delayed?
(Put another way, is it just a dumb idea to not include the standard transaction fee?  Is it possible for a transaction to permanently get stuck in limbo?)
•   Suppose the total coins you need to send exceeds the value of your individual addresses.  If you send out 1 combined amount from multiple addresses at the same time are you charged multiple transaction fees or just 1 fee?  (It sounds like you could easily combine less than 20 source addresses and get away with using just one .0005 BTC fee)
•   When getting change back for sending out too much,  does the change go to a different address automatically in all wallets? (my guess is: no, but it is possible?)
•   Is there a separate transaction fee needed when the change goes to a different address (a new change address) than the original sending address?  (my guess is: no)
•   Can you send from one address to multiple for 1 standard fee with having it be delayed? (my guess is: no)
