I assume the word "kinda" is a shortened term of "kind of." Then, does "needa" has the same meaning as "need of?"

Almost! "Kinda" is short for 'kind of." However, "needa" is actually short for "need to." Sometimes, "to" or "of" sounds like an "a" at the end of a word. Ex: I needa go now! = I need to go now! Ex: I coulda helped you sooner. = I could of helped you sooner.
