Yes, it's very important. Girls judge how you'll be in bed by the way you kiss. Most women love kissing and get turned on by making out so being good at it is important.
Some tips. Be relaxed about it, don't hurry. Watch your tongue, don't get it too rigid and avoid boring centrifugal movements. Don't stuff your tongue down her throat, be playful with it. Watch the dynamic of the kiss, start slowly just kissing her lips and prolonging it with each next kiss. When you start tongue kissing, again start slowly, tease her with the tongue, don't push it too far in, keep it soft. As it gets heavier, you can give more tongue and longer kisses. Use your hands to caress her face and play with her hair. Pull her towards you when it gets passionate. Chicks love push pull, so when it gets really heavy, you can hold her face with both of your hands and totally, but totally slow down, run your tongue across her upper lip and caress her tongue with yours really gently and slowly, then go full in really passionate the next moment.
Kissing involves two people. Watch your mutual dynamic, her reactions etc. People have different styles of kissing and sometimes it takes a kissing session or two to get your own mutual style that turns both of you on.
The most important thing is to relax, enjoy and just do what feels good.
