Jason re: the bugs...what SORT of bugs? The biggest problem with indoor plants is usually fungus gnats that will not hurt your cham but they are annoying little guys. I know we did a thread about these awhile back. If you keep the soil too moist you are bound to have them. Eggs are in the soil and can remain dormant until proper conditions arise - excess water.
As for sterlizing soil you need to bake it in an oven at 160 for 1/2 hour. Nuking will not work b/c it retains moisture - not worth the effort- and DO NOT put the whole plant in the microwave as someone suggested unless you want a mess and dead plants!
