Moghler.... welcome to the forum. Don't forget to head over to Roll Call and introduce yourself and tell us a little bit about yourself and your smoking equiptment.
Now for your smoker..... look in the forum for charcoal smoakers. You smoker is what we call a horizontal offset smoker - meaning the smoke chamber is set off to the side, it is very similar to the Char-griller and Char-broil smokers. With these types of smokers there are some very easy and cheap mods you need to make to turn them into a good smoker.
Use heavy duty dryer tube to lower the exhaust stack down to level of your main cooking grates inside your smoker.
Either purchase or build a charcoal basket for your firebox, this allows you to use the minion method which is where you get long burn times.
Make some sort of baffle and/or tuning plate to help even out the heat distribution from the firebox side to the non-firebox side of your smoker.
Get good thermometers! The factory therms are usually off by 50°-100° and will screw up your cooking.
I also highly recomend you sign up for the free 5 day e-course on the home page. It will start you off with some good solid basic info.
Best of luck and don't be afraid to holler with questions. We got a lot of good folks here willing to help.
Here is a link to a rather lengthy post that covers a lot of differant way to approach the mod's I mentioned above.
