I totally agree with everything Olstyn says, especially about different options. Personally for me, I don't like the poo cleanup involved with cresties, but I love my little girl... I'm just not getting another anytime soon.
As for being afraid of the bugs, honestly, I'm not a big fan of touching them either, but you do get used to it... get some antibacterial soap and wash. Let me give you some hints. One, no one likes lost bugs, so until you feel comfortable handling them, make sure you are escape proof. I usually suggest grabbing your shaker (for the vitamin dusting or whatever you are using) and your container of bugs and head to the bath tub. Seriously. You sit outside, the bugs and shaker go inside and you get a barrier to runners and jumpers. That way, if one surprises you by jumping in a way you don't expect, who cares, it can't climb the walls of the tub and if it is on you, you can shake it off into the tub. Worse case, you can smoosh it there too if it was an extra. (In fact, I still have a similar setup only we use a spare 5 gallon container which holds the smaller cricket keeper inside. That way if I loose one, it isn't going far.)
Another good thought is papertowel tubes. The cardboard leftover when you are done with the roll. Crickets like to climb these things. We just place it in the cricket container vertically, wait for one to wander up the side of the tube and quick move the tube into the shaker and give it a good shake. Cricket falls off into the shaker, and you are a good 8-10 inches from it at all time. 
Please feel free to ask any more questions you have, we are really happy to help. And let me please thank you, thank you, thank you, for asking questions BEFORE having the gecko in your possession. We are ready and willing to answer questions then, of course, but it is so much easier on everyone (especially the gecko) to have as many concerns out of the way before you set up the little one. A huge gold star for you for thinking ahead. Good luck, we are happy to help in anyway.
If you do consider Olstyn's thought about crested geckos, there is another forum right here for them. It might not be a good time to visit though, I may have accidently started some sort of flame war by suggesting Kingsnake is a good website and some poorly interpreted humor. Ignore my thread and you will find some good help too. Take care.
