If you check out " Looting. what's good and how to get it.
" there are some good ideas (I ranted on a bit about useful tips for starting, if you can sift through my poorly worded text, plus all the other info people have posted).
Also there is Noises guide to the Wilderness, maybe not the new starter stuff but definately the next stage up with tips on what items to go for to survive (ie get your ass away from towns and learn to live of the land as much as possible).
Oh yeah, and since it's for new starters you could mention that you only have one Survivor per copy of Arma II (You sort of come across that but don't explain why it's the case)... so Profiles mean nothing other than a name or look, as it will still load you into your previous game, just with varying looks/name tag.
When you mention Beta (for updating) some people think that we mean DayZ, so it might be worth mentioning that for the best experience its the latest Arma II beta patch (along with the latest DayZ mod patch - I don't use six updater, just some program called 'DayZ updater' since I already had it running, using this for any new patches) - only because I've seen on the DayZ mod forum new players getting confused over this.
Hope this helps.
