Since the series takes place between Episodes II & III - the Fett in question would have to be either a previous hologram recording of Jango or present Young Boba or another Mandalorian all together.

It has to be the same alien race since Zam is long dead at this point.
I'm hoping that's a young Boba though.

Could it be some backstory with Jango and Zam? Seems pretty redundant to come out with a new Mandalore and shapeshifter character in this fashion.

Could be. However, we've already seen Aurra Sing on this show. If memory serves, she runs into Boba a lot in the EU while working for Dooku. So I wouldn't be surprised to see a young Boba show up on this show at some point.

The Fett-style helmet appears to have decorative wavey stripes above the forehead which could indicate another Mandalorian entirely. There is also a shot of the holocron cube which I guess is used to hold historical hologram records.

Based on the full shot of the "Fett" hologram, it appears that he is wearing a serape like the one in the concept art below.

About the Holocron. Some info what the story could be.
"A ruthless bounty hunter infiltrates the Jedi Temple and attempts to steal their most guarded secret. It's up to Anakin Skywalker and Ahsoka Tano to stop the bounty hunter before he can use the secret to bring an end to the Jedi forever."
The Holocron Heist is a story found in the second season of The Clone Wars Animated series, adapted for young readers in a book published by Grosset & Dunlap, part of the Penguin Group. Look for it at bookstores this Fall.
