Some people develop sensitivity to CA causing respiratory, eye, and skin problems. CA is expensive in comparison to alphatic resins. In some instances, the additional working time that alphatic gives is a real plus. I've heard some claim that over a long time, alphatic joints will outlast CA. I use both in my builds. For assembly purposes, the epoxies available at the lhs are fine. Generally, the longer the cure, the stronger the epoxy.
For sources of tools, of course, there's the LHS and local hardware store. I like to keep an eye out at a number of tool stores in my area. Also, be sure to check out Harbor Freight. I wouldn't call them top quality, but you can find some useful items at good prices there. Check out MicroMark. They have a good selection too. Don't forget checking out the auto parts store, the craft store and art supply stores too.
Paul Johnsons' website, www.airfieldmodels.com, is a great site. If you are interested in scale, check out Dave Platts' website for his video collection on building.
Drilling holes into all but the smallest ribs should be fine. The biggest challange is having the ribs properly aligned.

BTW, my favorite tool: RCU!

Good building!
