To learn how to use tobacco pipe is fairly easy, 

for the Most people use the three-two  method as it is sometimes referred. 

before you use it, make sure you have the right tobacco pipe,  wood one are most perfered, there glass tobacco pipe or stone or metal one, but the most popular most recommend one are wood tobacco pipe,

once you have a wood tobacco pipe,  you can buy tobacco in almost all the cigar tobacco or smokeshop, which is  means first you take your tobacco fill the bowl full then use the tamper to press it down with a bit of pressure. Then repeat two more times each time pressing down a bit harder. When you pull on the pipe (prior to trying to light it) it should have the resistance of pulling a drink through a straw. If it pulls to freely or too hard empty the bowl and start over.

you may also find tobacco pipe tamper or reamer, to clean up the tobacco pipe mouth steam, or the holes inside the bowl to prevent clogs, 

Once packed use a wood match to steady puff circulating the match around the bowl. The tobacco will rise and go out. This is called the charring or "ghost" light. Now strike another match and repeat the process until the tobacco is going from a stead puff. Do not pull to eagerly or the tobacco will burn too hot. Slow and steady wins the race. Remember smoking a pipe is relaxing not a manic affair.

It takes a lot of practice to pack a bowl well and even more practice to keep the bowl burning longer than a few minutes. There is no shame in lighting the bowl as needed.  to avode that light up your tobacco pipe, many people use a hemp, its little roll of raw hemps, you light up the hemps first, and use the hemp to light up the tobacco pipe, doing so will avode burn your tobacco pipe,

Any tobacconist will gladly walk you through the steps and help with finding blends to try. I recommend buying an ounce of a few different ones that sound appealing.
