Hi Everard,
A quality tripod is almost mandatory for binos that big -- they are too heavy to hand-hold except for very short periods. One old, old trick I picked up from others years ago is to use a broom as a "monopod" -- get out a kitchen broom, turn it upsidedown, put a towel on the top and the head of the broom becomes a binocular rest. I use it all the time.
You have to hold 'em on the rest and can't let go. Need to find the right length broom-handle though! Just helps to support the weight but it is still very difficult to observe at zenith. Works great up to about 60 deg elevation.
As for objects to look at a good starting point is here:

There is also a binocular highlight column in AS&T but it only covers one object at a time -- might be worth a look.
