In reply to question #3, it would be best to set up the modchip, get it running and flashed with OS v1.1. Second, install the HDD after the modchip and OS 1.1 is working 100%. Then, you can either use Slayers to install Evo-X dash or do it manually with one of the great EvoX tutorials. Evo-X is the easiest to install and learn with. After you understand how the modchip, HDD, and dashboard all work together, then you can change to Avalaunch or any dash of your choice. Avalaunch is a great dash. But it has many options that can be confusing if it is your very first custom dash. It's better, IMO, to start with a simple one like EvoX, get it working, learn how to do simple tasks like change menu items, etc., and then install the more complex dash like Avalaunch later. You'll understand more about what you're doing and how to do it.
