Being a 1.0 CE owner you will have all your 1.0 CE items (onion helm) and all the new CE 2.0 Items. Early access was givin to only legacy players (players who payed for a sub during the legacy event). All other players need to preorder a new copy( if you own a CE DO NOT buy the CE again it will not work, just get a reg copy) of the game to get a pre order code which they have started taking already.
If you just stay with your 1.0 CE edition you will be able to play on the 27th.
I Preorderd a new copy( I am a 1.0 CE holder like you) for the items and the early access. It was worth the money to me but some might not see it that way.

One thing that confuses me about your post is that you preordered a new copy for items. Do you get some different items for a preorder of ARR as well?
The reason I'm asking is that I'm actually going away on business for a month soon, so I basically would get to play the game for a couple of days and then miss out. So, the early start is actually valuable to me. If I get some new items on top of the early access, that would definitely tip the scale towards eating the $30.
