I didn't mean to discourgae you from starting! Just hoped to enlighten you to the extremes of uilleann piping.
I had my first opportunity to play several sets about three weeks ago. One was a half set (bag,bellows, chanter, and drones) and a full set (bag, bellows, keyed chanter, drones, regulators).
First impressions:
You can't play the chanter like you do a whistle. Th fingering is fairly different. Now, that being said, you'll have a start on the pipes if you DO play whistle, because you understand how your fingers need to move to cover holes, and you know something about the music.
Also, you have to learn how to breathe all over again. This time with your ARMS! Since there's no blowpipe lke on Scottish pipes, you inflate the bag with a bellows. You also overblow the chanter to get the second octave as in a whistle.
Now, you can play the U pipes without drones or regulators and just use the chanter, but be warned...if you turn on the drones or regs in mid tune, you will suddenly need a lot more air from the bag, which also means more pumping with the bellows!!
As you can see, this is pretty complex already! The problem I had was trying to remember that I had to fill the bag with a bellows, and that each squeeze of the bellows meant a slight release of pressure on the outside of the bag. If you don't release the pressure on the bag from your arm, you'll get a rise in pitch of whatever note your playing.
It was indeed difficult, but then i only played each set for like five minutes. Hardly enough time to become a virtuoso. I'd guess you'll need at least a solid ten minutes for that!
Hope this gives a little better understanding of the dynamics of this amazing instrument!
