Episode VII - Heir to the Empire
Episode VIII - Dark Force Rising
Episode IX - The Last Command
Don't oversaturate the market. At most, continue printing existing materials, along with supplementary products for the films, i.e. figurines, posters, art books, data files, etc. Wait for at least one year after Episode IX before announcing the next project, and don't air it until a year after that.
As for what project...either a live-action adaptation of the Rogue Squadron novels (you want more strong female characters...allow me to introduce Ysanne 'Ice Queen' Isard, Director of Imperial Intelligence) or an animated adaptation of Dark Empire. Either way, whichever doesn't get picked gets the next slot after the previous one finishes. Minor retcons for Dark Empire, just to set the timeline, with Dark Empire's events now taking place after the Thrawn trilogy.
After that, assuming Disney still hasn't booted me off, it's off to the past, with a live-action adaptation of Knights of the Old Republic. Two seasons each for Revan and Meetra's respective story arcs, plus a standalone movie to depict Revan's final doomed mission to Dromund Kaas, with succeeding events explored in the ongoing MMORPG The Old Republic. Maybe a supplementary comic series, with each of SWTOR's PCs getting their own distinct future timeline, i.e. what happens in the timeline where the PC was the Jedi Knight, the Consular, the Bounty Hunter, the Imperial Agent, etc.
Finish Star Wars Legacy, and then maybe Episodes X to XII adapting the Jedi Academy trilogy. Skip most of the succeeding novels, which were all meh, and go straight to NJO. Animated adaptation? Not too sure...again, NJO is hit or miss at the best of times, then again, the same can be said for Filoni and his version of Clone Wars (only Tartakovsky's version is canon for me), so could work, if not really into it.
If Legacy is to be adapted, make it live-action. After that...let's go back to the distant past, with more animated adaptations of either the Dawn of the Jedi, the Great Hyperspace War, or the Great Sith War. That, or the New Sith Wars, focusing on the rise of Darth Bane, the Ruusan Reformations, and the seeds being laid for the ultimate downfall of the Republic.
