Would it work to connect the guitar to my Ion speaker? Or does it need a dedicated amplifier?

I'm not sure if the Ion speaker will work, but the guitar will definitely need amplification. The signal coming out of the guitar is not strong enough to be heard unless it gets amplification from somewhere.

Can you put a floyd rose in it?

No. The body would need a cut out to go forward and back with a floyd rose.

Rosewood or maple fretboard? sharktooth or dot inlays? pictures and description don't match. what exactly am i buying?

It is as pictured with maple and dots, the description Amazon used is not correct. The purple is a bit darker than in the photos in real life too but only slightly.
