What you are looking for is the Dark Horse Comic Series "Dark Empire" (& "Crimson Empire" as an extension), which depicts the events after the Thrawn Crisis and involves the "Resurrection" of Palpatine and the last major Clash between the Galactic Empire and the New Republic, well the final one of great scale at least. You can read the summaries on http://starwars.wikia.com since the comics aren't that easy to get anymore.
