With the Alclad I spray it at a lower pressure than other paints.Normally about 5 psi. Its all personal preference though.Although the website recommends using the airbrush in a "paint brush style",I found it worked for me to mist the Alclad on and gradually build it up that way.As you say,,its practice and finding out what suits you best.
The gloves I use while handling an NMF plane are the white lint free gloves that you see people handling photographic negatives with.
The Alclad dries quite quickly,probably a bit quicker than acrylics, but I would leave it to dry overnight before starting to mask the different panels.
I use Tamiya masking tape,and stick it to the back of my hand a couple of times to make it less adhesive.It will still give you a good straight edge and this is just a preventative measure in case it tries to pull the base coat of Alclad up,but this has never happened to me.(yet!)
Hope this helps.

PS,,if you find you get a run or a pool of Alclad,just stop the paint flow and blow the pool to spread it out and this will blend in.You have to be quick though. :-)
