I need help with this maximizer i am a noob to this so please dont flame if im well newbish...

Heres my config

Code:
# 
# WoW Maximizer configuration file 
# 
# Open Readme.html for instructions. 
# 
# Lines starting with '#' are ignored. 
# Remove the '#' from a line to use it and set the values you prefer. 


## Display resolution. Leave this out to use the current display mode. 
# resolution = 1680x1050 
## Display device. Leave this out to use the primary display. 
# device = 1 
## Keep the taskbar visible. Leave this out to use the whole screen. 
# taskbar = 1 
## Make room at the bottom of the screen (for autohide taskbar). 
## Arguments are top,bottom,left,right 
# margin = 0,1,0,0 
## Increase screen brightness (gamma). 
# gamma = 1.7 


## Example 0: Use the current display mode and primary display. 
# 
-nothing- This is the default behaviour. 

## Example 1: Use 1600x1200, 32 bits per pixel, any refresh rate. 
# 
# resolution = 1600x1200 

## Example 2: Use 800x600, 60Hz, 16 bits per pixel. 
# 
# resolution = 800x600 
# frequency = 60 
# bpp = 16 

## Example 3: Use display 2, do not change display mode. 
# 
# device = 2 

## Example 4: Use display 1, change display mode to 1024x768. 
# 
# device = 1 
# resolution = 1024x768 

## Example 5: My settings. Use 1600x1200, 75Hz. 
# 
# resolution = 1600x1200 
# frequency = 75 

## Example 6: Keep the task bar visible, use the current display mode and primary display, 
# 
# taskbar = 1 

## Example 7: Keep the taskbar visible if set to autohide and located at the bottom. 
# 
# margin = 0,1,0,0 

## Example 8: Increase screen brightness (gamma). 
# 
# gamma = 1.7 

## Guild Wars (not 100% functional) 
# 
#program = Gw.exe 
#title = Guild Wars 
#class = ArenaNet_Dx_Window_Class

I have read other Tuts im just a bit stuck, also do i need 2 wow folders to acheive these setting?

i have read some Tuts but there a bit confusing still can someone lay down the basics of the basics pls, would be nice

I am thinking of testing out on a private realm, just to see the level rate or duel boxing if its quicker or what etc etc, i will probably choose the paladin class or warlock/priest
