If you are looking at tweaking every aspect of your Mac install to they way you want it to work, but your not a huge fan or confident using terminal and the text editors then you should give Secrets PrfPane a go.
PrefPane installs into your systems preferences interface, and displays all the possible (known) tweaks in a simple easy to use interface. Making switching options as easy as placing a tick in a box. Secrets is a community based website, with tips and tweaks being added all the time, the PrefPane has the facility to download the latest tweaks at the push of a button!
One thing worth mentioning: As you may well be adjusting system settings not normally visible to users you may want to consider using TimeMachine or something similar to back up your system before making changes!
