A question or two about transactions...

Having looked at various MLB sites I'm struggling to piece together a solid understanding of how baseball contracts work and in particular the details of intra-club transactions.  I've put together a brief summary of how I think things work but if anyone can validate the meaning of the following types of transaction I'd be very grateful?

"player A has been selected" = added to 40 man roster for the first time having been signed/drafted by the Major League team

"purchased the contract of player B from AAA-Sacramento" = added to 40 man roster for the first time having been signed to a minor league contract

"player C has been optioned to AAA" - removed from active roster but retains place on 40 man roster

"player D has been recalled" - added to active roster, having already been on 40 man roster

"player E has been outrighted to AAA" - removed from both active and 40 man roster, but remains under club control

"player F has been sent down" - same as player E?

"player G has been called up" - same as player D?

Also, what is a "conditional deal"?
