Featuring other Jedi is a tricky game because you need to build audience interest and care regarding all the other knights and masters, but you don't want to diminish the nature of Kenobi or Skywalker by having a bunch of other people do what they do. My compromise is to have various others appear and play their parts, but many of them are not as involved directly with the armed forces like Ben and Anakin.
You have Jedi medics, pilots, builders, engineers, the works. Prior to the war starting there's references to Jedi creating music, art, writing, all kinds of things. Make it clear that being in touch with the Force went beyond just defensive and offensive moves in combat, and that something genuinely beautiful was lost when they were wiped out. Put Luke's journey in the original films as just beginning to regain the extent of what being a Jedi with the Force really meant.
I've also been debating whether or not to hint at their mythology and lore, with Ben telling Anakin of the legend about Darth Vader, the earliest known Jedi to have turned to the dark side (which he did in order to supposedly save his fellow knights from extinction), with Skywalker later taking the name in the third prequel as a personal act of defiance against Kenobi.
Certainly it's tricky. That's kinda the point ;P. You want to show what the state of Jedihood is, but also try to give them personalities. It's a careful balance to strike, but I believe it's a necessary component to give the story its full potential.
