How old she? Something like 19 or maybe early 20s by the time she fights Maul on Mandalore (final 4 episode arc) Then add whatever amount of time to her Rebels stint, and then again for when she shows up in The Mandalorian
-How/when in the Star Wars timeline was she introduced? Introduced as Anakin's padawan in the animated Clone Wars Movie, which takes place sometime between AOTC and Revenge
-Does she have an interesting backstory? Anakin's padawan, lots of adventures during the clone wars, ends up being framed by another Jedi padawan for bombing something, leaves the order after she is exonerated by Anakin. After TCW timeline she bounces around hiding until becoming a key piece of the Rebellion for Bail Organa
-Does she have any major history/romance/conflict with anyone? Nothing here, as far as I know. She and Anakin become very close friends, and she is loyal to and respected by all the clones she leads
-In general, how would sum up her overall plight? Goes from annoying, snarky padawan to pretty much an awesome Jedi/force user, and one of the best characters in SW. In the Rebels era she has to come to grips with finding out Anakin became Vader, and has a confrontation with him.
Any other broadest of broad plot strokes I need to know heading into the final four episodes? Just that she left the order after she felt they didn't trust her, or have her back enough when she was framed. She does have a slight history of encounters with Maul.
This is all from memory, and there may be a few more things others can add.
She ends up becoming an instrumental figure called Fulcrum and works closely with Bail Organa in forming the Resistance. I also recommend after watching the last 4 episode to watch Twilight of the Apprentice to see her and Vader reconnect for the first time.
No real relationships as mentioned but there is a scene in the final 4 episodes between Anakin and Ahsoka when he returns her lightsabers to her that tells you everything in their relationship. There is an incredible bond, and you can see how Ahsoka leaving the Jedi Order after being framed plays a pivotal role in Anakin's doubts and eventually turning to the dark side. She is a critical voice of the jedi. She is no sith, but she rightly calls them out as no longer being defenders of peace and only being the galactic soldier. She becomes a voice of reason that Yoda only begins to realize himself in the weeks leading up to Order 66.
The clones are incredibly loyal to her and in the final episodes paint their helmets to match her skin patterns. Her white lightsabers from Rebels are after she purified the corrupted Kyber Crystals of an inquisitor.
The Clone Wars as a whole retroactively makes the prequels better across the board. Anakin has more character, a little bit of a cocky Han Solo going on. Obi Wan is incredibly fleshed out and we learn that he almost left the Jedi Order because of his love for the ruler of Mandalore when they were younger. (That ruler's sister is voiced by Katie Sackhoff as is the last known owner of the Dark Saber before Moff Gideon)
