I just found this information, but am not sure a) if it solves my problem and b)how to use it (especially without a terminal.) Any advice would be appreciated.
For those interested here is a link for Apple 15 aluminum powerbook info: http://tstotts.net/linux/gentoopb.html

(this is a wealth of info for all types of hardware.)
Most versions of X11 support 3-button mouse emulation; however, it is not as configurable or robust as the kernel solution. If compiled-in, the kernel supports 3-button mouse emulation, configurable via sysctrl.
# zgrep '^CONFIG.*EMUMOUSE' /proc/config.gz
I prefer the ENTER key as Right-button and Fn-ENTER as Middle-button, where ENTER is the keypad enter key adjacent to the right-hand Apple command key. This way, the emulated buttons are adjacent to the trackpad itself.
# sudo grep mouse /etc/sysctl.conf
dev.mac_hid.mouse_button_emulation = 1
dev.mac_hid.mouse_button3_keycode = 96
dev.mac_hid.mouse_button2_keycode = 127
To use an external USB mouse, the kernel module usbhid must be loaded or compiled-in. Interestingly, some USB mice misbehave after a suspend-to-ram or a lengthy idle period; and they will never operate again unless plugged into a different USB port or a reload of the usbhid module. One such mouse with these troubles is: Kensington PocketMouse Pro Wireless 72117.
An adequte work-around for troublesome USB mice (and keyboards) is to compile the module usbhid as a module rather that compiled-in, and reload as necessary.
# zgrep '^CONFIG.*USB_HID' /proc/config.gz
# modprobe -r usbhid
# modprobe usbhid
