The first thing I would do once you can get into OSX is to backup your extensions folder and kernel. That way if you install something and bork your install you have a backup copy and a 5min fix instead of a full reinstall. Ive included directions on backing up those files at the bottom of this post.

Backing up your Extensions Folder & Kernel Using Terminal
In short:

Code:

sudo -s
mkdir /backup
cd /System/Library
cp -r Extensions/ /backup/
cp -r /mach_kernel /mach_kernel.backup

Steps explained:
1. Give yourself root privileges so that you can modify files.

Code:

sudo -s

2. Make a backup copy of your kexts. First we will make a directory called "backup" in our root directory to store them. Open Terminal and type:

Code:

mkdir /backup

3. Change directories to /System/Library This will shorten some of the commands we have to type in.

Code:

cd /System/Library

4. Copy your kexts to the new "backup" folder.

Code:

cp -r Extensions/ /backup/

5. Backup your kernel (Using mach_kernel.backup as a boot option will load your backup)

Code:

cp -r /mach_kernel /mach_kernel.backup
