The first part of getting adjusted to EQ2 is going to be realizing the UI is a lot more restrictive -- there's simply lots of data we don't get and things we can't do that are possible with your other game's UI
For the first, I recommend EQ2MAP. It has a search for various points of interest (which are displayed on your map). You can also use eq2i.com via the in-game /browser command to look up quests.
As for auctioneer... that's a no. If you want to watch the market, you have to do it yourself in EQ2.
