the settings on the H2 are : Front 90, Rear 120, and all four together... I tend to use Stealth (external) mics as they're easier to get to head height, and you can stash the recorder (once you set the levels and locked it down) in a pocket or bag.
If stealth *isn't* an issue, the unit stands quite nicely on the rubber feet...
I've been recording since 1975 and it's always tricky getting the right level... with the H2, I set the attenuation to Concert and start with a level of around 85 (it goes to 125) You can adjust while recording, and balance it out later, but TBH, setting the level during a soundcheck, or support band is probably best.
Leave some overhead just in case, set the peaks to around -6dB to account for loud claps/explosions/etc...
But really, the best advice is to go and record something... in a pub or free gig... just to get used to the rig.
My favourite rig was the Walkman D6. it never let me down. despite having to flip tapes (under 2 secs, with practise)
I can't really say I hate this since I'm too dumbfounder to really know what to make of it, but...
