I'm assuming you meant "1/3 HP" as Little Giant doesn't make a 13 HP model.
There is a small black circle plug on the outside of the pump body with 4 holes dimpled in its surface. That's the oil fill port. You can turn it carefully using the points of a set of needle-nose pliers or snap-ring pliers. BE CAREFUL not to damage the plug, you're going to need to reuse it. It's sealed with a small o-ring (generic o-ring size '012'). Drain the old oil from there, then fill slowly thru the same port. There is a small amount of airspace required inside the motor so don't fill the motor completely full of oil.
If the oil needs replacing, there's probably another problem with the pump that needs to be addressed as well.
Yes. Float-type and diaphragm-type are both available as a piggy-back to your power cord and will work with most common sump pumps. Search 'Little Giant', 'SJE Pumpmaster' , etc. You'll have a good start with those.

If you have any water at all coming into the sump, there will always be a little in the bottom unless it stays dry long enough for it to evaporate. The design of the pump doesn't let it pump the last little bit out. If there is not a check valve in the discharge pipe, what is left it the pipe going out will drain back into the sump. If the discharge pipe is connected to the house drain and there was not a check valve in that pipe, depending on where the kitchen clog is, the sink could drain into the sump.
Yes it will power a small sump pump.
The pipe coming off of sump pump that goes outside or if allowable, a drain line.
If your pump is not cycling often the water in the pit will be stagnant and can get a little smelly or if the water coming in from the ground has a natural odor to it (like sulphur)
