I second the box of razor blades.  I never use exacto knives.  One thing you will want is a miter saw/box.  Otherwise you will be making angle cuts by eye.  It will work, but you will be happier when the cuts fit perfectly.  Probably have to go online for one of those in hobby size. 
When considering epoxy for joining the stabilizer to the fuselage and the wing halves together, you will want at least 15 minute epoxy.  30 minute will give you that much longer working time.  DO NOT consider 5 minute epoxy.  Before you know it you will be stuck.  Welcome to kit building.  Start a thread and make lotsa pics.
