am i doing this right?

OS: windows 7, have yet to try it in windows xp

okay i'm having a hard time doing this. i made it work but i want to know if i'm doing it the correct way.

i have my files setup like this:

___________
file # 1
___________

#mainfile
sys.path.append(r""path to normal folder containing ".sikuli"'s)
from clickevent import *

clickevent()

___________
file # 2
___________
#class/function file

from sikuli.Sikuli import *
#####sys.path.append("path to normal folder containing ".sikuli"'s) <-- this doesn't work i have to use setbundlepath
setBundlePath("path to normal folder containing the imageLib.Sikuli) <--- I have to use this instead... why?
from imageLib import *

def clickevent():
      click(button)
___________
file # 3
___________
#imageLib file

from sikuli.Sikuli import * <--- if this is just an image library do i still need this statement?

button = "IMAGE.png"
