You found the right place for help in working through these problems which most of us are prone to when beginning, these guys are the best! Like me, you are a beginner until you learn how to avoid these problems while smoking enjoyably. It really isn't difficult, you will get there! Here are some of my thoughts and ideas which are working for me, at a few months after being where you are now:
1. Pack the bowl gently, and fill three times. Fill once just allowing the tobacco to fall in, poke down light as a baby would. Fill again, and then a third time, press a little harder with each fill until it's compact, but springy. You should find when sucking air through the stem that there is a little bit of resistance, and believe me that little bit graduates from just perfect to way too much very fast! So test it once, and then test it again after pressing with a little more pressure. If the air that you draw doesn't whistle through the draw-hole, and you don't have to suck in your cheeks, then you should be fine.
2. Light while drawing, watch the top layer expand, let it die, tamp, and then light again. This initial charring light is SOP, it gets the rest of the bowl ready for burning.
3. Tamping should be done more gently than you think is necessary. You can always tamp a little harder, but a bowl too tight to smoke is a messy PIA!
4. Tamping compresses the burned ash down even with the still-hot embers, this should enable an easy re-light if the ash/tobacco proportions aren't too high - at some point you may need to dump the ash before you can continue enjoying the remainder of your bowl.
5. Re-lighting a pipe mid-bowl is perfectly normal and should not cause any problems with flavor when 1-4 are put to practice.
6. If you experience gurgling in your pipe, you need to do something about this! Get a pipecleaner and run through the stem down just into the shank, but not the bowl, then pull it out. Do this as often as necessary. Gurgling is guaranteed to produce tongue-bite!
7. How wet is your tobacco before you load it? If it leaves visible moisture on your fingers, then it should be dried out first. If it doesn't, then it should probably be dried anyway, unless it's already dry like paper. Like with everything else, others here can provide better advice on how. I've seen advice ranging from dry time of an hour to all day, but I being lazy like to put a bowlful in a toaster-oven pan and bake on 350 degrees for a few minutes. If you try that, don't scorch it!
8. How hot does your pipe get? When it goes from warm to hot in your hand, slow down your cadence! A hot pipe which burns a wet aro almost invariably has the wet gurgling going on. Draw lightly in small sips - pipe smoking is to be enjoyed and savored, while ring-blowing is for cigar smokers. When the bowl is hot, the tobacco which you are burning is too hot, and will release moisture into the bowl faster than it can evaporate out with the smoke. The bubbling of this in liquid form in your stem is not good for the flavor, and will burn your tongue. This won't happen with a dry tobacco in a pipe which draws well, or with good control of the heat level.
9. Try different tobaccos, especially non-aromatics. Most aros are difficult to enjoy for taste because they are so wet, especially the top-dressed cheapies which smell great when burning, but those watery dressings boil away faster than the tobacco burns, therefore you taste only the cheap burley. Good aros do exist, but they require meticulous mixing of quality burleys, and they have penetrative casings. Russ Oulette of H&H produced a great aro (Classic Burley Kake), but he subsequently announce that he would not produce any more new ones in that category because it was so difficult to make the flavor similar to the aroma (this one took him two years to get right).
10. Relax, and don't worry!
