Hi psycovic23, and welcome to Elysiun!
Have you discovered the IPO window? Select your lamp, and then press Shift-F5 to go to it.
Here you’ll find several bezier curves that are controlling the behaviour of your lamp, as set by your keyframes. You may need to change the combobox at the bottom to ‘Lamp’ instead of ‘Object’ for many of the characteristics of the lamp.
Move these curves by pressing ‘g’ as usual, or press tab to open a specific curve and edit its control points.
Advancing further, you may wish to use the Action Editor or NLA Editor to control your lamp, by grouping many different IPO settings into one ‘Action’. Read the documentation for info on them: http://mediawiki.blender.org of you haven’t found it already.
