I had a rad2 rapier as well, and I haven't used it on a heroic life since the change. It's not bad or anything, but there is probably stuff that is better. (Unless you can whip up a rad2 dagger, in which case go crazy.)
The vistani tree has been mentioned, and I would highly recommend it. There's a lot of power in the tree.
Apart from that, the biggest difference in the power creep in gear. It's HUGE. You will want/need to farm out some better gear for your toon, especially because content is scaled based on where the power creep was at the time of release. So newer content is significantly harder than older content. That affects you less at lvl 12, but it will hit you soon. Slave lords gear is nice, Ravenloft gear is awesome, and cannith crafting got a revamp and allows you to make the best stats for any particular level excepting end game epic.
For your assassinate DCs you WILL need better gear. I don't know what difficulty you are planning on running, but the necessary DCs have been heavily inflated for most of the epic content. You'll want your highest dex item (check out the newest released content in the Twelve for a +11 dex helm at lvl 21) as well as a high assassinate item.
Something else to know: if you run reaper, the random reapers that appear auto-detect sneak and not only find you but alert others to your presence. There's no real workaround for it.
