Read "Greater Than The Sum", then move on to the "Destiny" trilogy. Christopher Bennett (not to sound slavishly fanboy-ish but gotta give credit where it's due, folks) does an excellent job summing up the events of "Resistance" and "Before Dishonor" that lead into GTTS and thence to Destiny, and though there's not really anything in GTTS that isn't also touched upon in Destiny, your reading of that trilogy will be greatly enhanced by reading GTTS first. After Destiny, then you can read "A Singular Destiny", then "Losing The Peace", and then "Full Circle"...even if you're not really a Voyager fan, FC does cover some events that were kinda glossed over in Destiny.
Hope this helps.
