As of now the Halo: Reach beta is gone, your not going to be able to.

See halomaps.org for mods like sonic for halo. It is only for Halo Custom Edition, but you can convert it to Trial or Retail with Pearl or Demo with Queene Anne's Revenge.
google in halo mod database and click on the first one then scroll down until u see ilotzascarabmod and download that, but u have to have halo demo first and know how to work mods.
download mods is it a demo
Yes but it really depends where you download it.
you can download halo 1 demo but usually hard to find cannot rerally download halo 2 or 3
depends on what you're looking for. but most good mods in halo require a jtag. but a good site to look up mods is- http://www.thetechgame.com/
If you have Xbox live. Maps on halo 3 for mods. go to bungie.net, make a profile with your gammertag and look for the mods under community. just simply type in mods under the map seciton. it will automatically download to your 360 if you click download on it. I recommend planet mod.

No, you need 0.8.1
