How do I get it to default to say ttyUSB8?, cause all I am getting at
the moment is that it wants to connect to ttyUSB3 and it just ignoring
what it put in the conf file

Set up a udev rule for that particular device.

I'd second this: hard-coding to ttyUSB8 or similar could
potentially fail in the unlikely event you use up to that
number prior to plugging in the GPS. YOu can use udev to
provide a unique name, safe from clashes, such as
/dev/my_gps.

Add this udev rule to /etc/udev/rules.d/50-gps.rules

BUS=="usb", KERNEL="ttyUSB*", NAME="ttyUSB0"
