If you really want to check out some of the best of current Trek, IMO you might want to check out some of the post-finale series and novel only series, since they are both some of the best Trek out there, and what the majority of books are these days.
My favorites in order:
Vanguard: A novel series focusing on a space station in the TOS era.This series features a good cast of new character, intersting plot, and some fun ties into the later Treks. Easily one of my favorite Trek series in any format.
Titan: Follows Riker and Troi on their new ship after Nemesis. Also features Nurse Ogawa, Tuvok, Melora Pazlar, and a couple of recurring characters from some of the other novels. This series focuses alot on old fashioned Trek exploration.
DS9 Post Finale: The first post finale novel series, these books do a great job of continuing the story of DS9 after the end of the TV series. It also introduces some really good new (and one not so new) characters to replace the ones who left in the finale.
TNG Post-Nemesis: Baiscally does for TNG what DS9PF did for it. This series is a little more hit and miss when it comes to quality. I skipped over a few of them, but the ones I did read where really good.
Corps of Engineer/ SCE: An e-book series focusing on a starship beloning to the SCE. Also features a mix of new and old characters (most of the series do). The series is also being released as paperbacks collecting four and eventually eight ebook stories in each collection. I've only read a handfull of stories, but they were also good.
New Frontier: The first novel only series. These books are alot of fun, although some people complain that they can be a little to over the top at times. I've read these books pretty much since they started in the mid ninties, and other than a fall in quality twoards the middle, I've enjoyed most of them.
IKS Gorkon/Klingon Empire: A series focusing on the crew of a TNG era of a Klingon ship. I've only read one of these so I can't really form an opinion myself, although most people do seem to like them.
Voy-Post Finale: Another PF series, this one is just about to start again with a new author and new direction, after the original author left to due non-Trek stuff.
A couple months back we just got Destiny, a major crossover with characters from the casts of DS9PF, TNGPF, Titan, and the Columbia from ENT. The trilogy followed a major Borg invasion, and has had a big effect on the Litverse, that will pretty much continue from now on. The new direction of the Voyager Relaunch is a direct result of Destiny.
I'm not trying to say you need to read all of these, these are just the series that are going on right now.
