There are many schools of thought on this subject. I changed my oil at 2k, many would change at 500 or 1k.
What you can be sure of, is that it won't do any harm - quite likely a benefit.
There is a routine to prime the dry sump reservoir once the oil is out (taking the oil out requires some suction too I think). From memory you need to turn on the ignition, put your foot on the gas (all the way) and turn the engine over for 10 seconds or so.
Lifting the car needs considerable care - are they equipped with the lifting pads? There's a risk they could damage the underside without...
However, this should be verified by others on this forum. Have a hunt through some threads on oil change (technical stickies etc).
Hope this helps.
