Henke, yes, you could learn to play a normal right-hand set, since the whole thing will be new to you any way. Some lefties do this. However, each set is made to order, so why not get a left-hand set built right from the start? The only drawback I can think of in getting a left-hand set built would be that your resale opportunites would be much more limited if you later decided to bail.
The most often recommended course is to start with just the chanter, bag and bellows (beginner’s set). Later you can add the drones (half set). the next step is to add the tenor and baritones (three-quarters set), and finally the bass regulator (full set). Many people start with a half-set, but then realize that they have more than they can handle with just the beginner’s set, and only later understand they could have left out the drones for a few years (yup, I made this mistake, too).
You have some additional choices even when getting just a beginner’s set, and that is whether or not to get additional keys. You can get keys added for some of the more difficult notes (Cnat and Fnat), or enough to make the chanter fully achromatic. If money is tight, you don’t need any keys. The cheapest chanter has no keys, and has no mounts for adding keys later. Add mounts for future keys and the price of the chanter goes up a little. When you want to add keys later you will have to return the chanter to the maker for several weeks. The more keys you add, the greater the price (again).
If you play whistle, there are a few differences on UPs. Whistle is open ended, whereas the UP chanter is played closed against the leg. You have to lift the chanter off the leg to play bottom D. The middle D on whistle is played by overblowing the 2nd D, whereas the UP chanter has a hole in the back at the top for reaching this note (usually referred to as “back D”) played with the thumb of the upper hand. The extra hole you refer to on the front is D#/Eb, so playing E is a two finger movement instead of one like on the whistle.
The other difference between playing whistle and UPs is that UPs are usually played in what is called “closed style”, i.e. you lift the fingers to play a note, but then close them again to play the next note. UPs can also be played in “open style”, which is closer to the method used for playing the whistle, but the tone is a bit different, and many people frown on this style.
If you want loud, then the term usually used by UPers is “wide bore”, which refers to the internal diameter of the chanter. Wide-bore UPS are usually louder, with a bit more strident tone than narrow-bores, which are quieter and sweeter in tone.
What makers are good? Check the many threads on this forum to see who UPers like (notice how I duck this to avoid controversy)
. One of the best recommendations I can give you is to find a maker near you, so that you have easy access to go back and ask questions, complain, bitch, moan, and all the usual carry-on. Here are some lists of links to various makers:

One thing you should note is that different makers have waiting lists of various lengths, depending on their outstanding orders and how full a set you order; anywhere from 6 months to 15 years (yes, really). You will have to shop around.
While you are waiting, buy a tutor like Heather Clarke’s, and see if this answers your questions.
