I need to be come more skilled at identifying player types, lines and tendencies for the purposes of better identifying their range.

I split player types in Stars using the tabs like this:

Blue = Fish (e.g. 30/15)
Orange = Maniac (45/35 + Spewy, uber bluffy etc)
Red = Nit (e.g. <13/9)
Purple = TAgg (e.g. 19/17)
Turquoise = LAgg (27/22)

1) Are these fairly accurate?
2) Can anyone link me to any good reading on this?
3) What are your own thoughts?
