Ubuntu :: Running Scripts At Start-up?

I'm afraid I'm having quite a bit of problems with getting some processes to run at start-up. There are two problems I'm having - the first is that my wireless won't work at startup until I go into terminal and use 'sudo modprobe b43', and the second is that I want to automatically mount a hard-drive partition. So far, I've tried two approaches.

The first is to create a shell file, wifi-fix.sh, containing the following text:

Code:
#! /bin/bash
modprobe b43
mount -t ntfs-3g /dev/sda7 /media/Documents -o force

This was put into /etc/init.d, and I used 'chmod +x wifi-fix.sh' to change the attributes. Then (if memory serves - it's been quite a while since I tried this method) I used the command 'update-rc.d wifi-fix.sh defaults'.

That didn't work, so I tried adding the last two lines of the above code into /etc/init.d/rc.local.
