Second Hand RGH'd console - noob questions

Hi,

I just got a modded Xbox 360 S, the seller says it's RGH2. Seems to be a Corona. Has the following installed:

• Xell Reloaded v0.993
• Freestyle 3 v3.0b rev775
• Kernel v2.0.17150.0
• XeXMenu 1.2
• lots of games.

I can boot into Xell with eject, and into the default dashboard with RB. I could not find any trace of Dashlaunch, or I don't know hot to start / boot into it.

I have the following noob questions:

• Is it OK if I restore factory defaults in the original MS dashboard? I want to start fresh with games, emulators etc.
• Can I safely connect to the internet? How do I do that without Dashlaunch?
• Can I install Dashlaunch and replace Freestyle with Aurora? Will these conflict with the software which is already installed?

Thanks!
