Needed to change bottom baking element. Was stupid and did not unplug it before I pulled out old element. Sparked 
Now entire oven and stove top does not work. What do I need to replace now?

You can see that there is not a unit with a 0 between the W and B.
Since both the oven control and the stove top elements do not work, it sounds like a power problem.
The two are usually separate circuits in a stove.
So I would start by checking the power.
Try flipping the breaker off/on slowly a couple times, sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.

If OK then unplug it and check that you have not burned off a wire that is common to oven and stove top (very few have one)
I cannot tell if the unit has an internal fuse. It is a GE and they like to keep everything a secret.
Do not be surprised if when you get the stove top working that the oven does not.
This usually blows the control board/timer.
