Burn for ice is just fine... afterall, you feel like you got burnt if you do get a frostbite. Meh, I won't specify what moves a Pokemon should learn what really. Just make the moves first ;p
Bug Bite is a bit overpowered... 50% toxic is insane for that power. Either drop attack power or rate of effect, or toxic becomes just poison instead. >>; Plus Pinsir doesn't exactly "bite?" Some other "bite-y" Pokemon should learn it too, to diversify bug attacks on to other types. Of course, this means that frostbite will also have to be changed as well. 50% freeze is bad, and doing that much damage is chaos.
As for Lightning, I'll lower accuracy to 90% to be similar to the rock slide level. The power of bite is a bit too weak, and right now it's a bit too strong. Having the same setting as rock slide seems reasonable. Not weak into the "only use this if desperate" category like bute, but not too strong so it's obviously a better choice over thunderbolt either.
Hm... I'll write a few unoriginal stuff here.
