I think the name itself is lovely and i don't think she will get any stick from it, she will likely shorten it to Tali herself even without any knowledge of the source of her name, it will be a natural contraction and i suspect that by the time she hits highschool it will not be the most unusal name out there.
One thing i would say however, is that you may well have caused your daugher a different kind of problem, the apostrophy in her name will make it all kinds of hell for her when trying to fill in many forms and registrations. My last name is hyphenated and that, despite not being that unusual, causes me all kinds of problems. I was once denied the ok to rent an appartment as a result of the referencing service not being able run a check on me because their software would only let them input letters in the surname field. It has also prevented me registering with some websites and services where you have to submit your full details and the registration won't accept hyphens in the surname.
I would personally have split the Tali and Zorah into first and middle names but only for that reason.
Anyway best of luck to you and your daughter.
