as for lighting.. i wouldn't use anything other than a match (preferably wooden) as the fluid from zippo lighters tends to make your cigar taste like lighter fluid, although a butane torch is ok if make sure to light it evenly.
cigars, in my opinion, are best enjoyed with a good drink in a relaxed enviroment. use your cheap ones during the poker game with your buddies, and only bring your good stuff out for smaller, more personal settings
i agree with jorgelito, go down to your smoke shop and talk with the owner, chances are he'll be more than willing to tell you all about everything you never wanted to know
if he isn't a smoker himself, he should be able to tell you where you can find the info your looking for.
