Wouldn't the moon nazis take care of that for us?
OT: What ship types are in their invasion fleet then? By what means did they arrive(FTL, sleeper ships, stargate, e.t.c.) here and are they human like or monsterish?
Only MASSIVE transports with point defence, but they have some large in-atmosphere craft that utilise anti-gravity tech to make them floating fortresses. They have limited FTL; they can't fire FTL projectiles or anything like that, and it still took them quite some time to get here. In appearance, imagine a humanoid tardigrade.

What's the biggest problem that forced them to move- lack of space, food, a spreading disease, or is their homeworld doing reasonably fine, and they're purely expanding for the hell of it?
Lack of space on their homeworld plus a huge breeding rate. They don't have much in the way of terraforming, either, which is why they need a world similar to a more pristine version of their homeworld. Ours will suffice.
I'd imagine you are doing this as research for a piece of sci-fi writing, and I agree with what other people have said. An alien society capable of not only understanding, but controlling relativistic space travel would likely have a vast grasp of physics and quantum physics that can be utilised offensively and we can't even comprehend let alone defend against it.
Perhaps a more suited method of transportation, if you would like them on a "relatively equal" field in terms of technology, would be generation ships or cryogenic transport. It is a method of transport that humanity itself is close to and possibly already developing, so it reduces the potential intelligence of the aliens down to a more equal field that allows you to utilise more conventional warfare and give the humans (presumably the protagonists) a fighting chance.
That said, the best you could get out of a plot like that is something akin to Halo or Starship Troopers, with a bit of colonisation and xenophobic sub text, and human patriotism. But since I don't wish to tell you how to write a story, the answer to your question is that humanity would do anything and everything in its power to survive, including commiting war crimes and using chemical and biological weapons.
