Planet with two moons and rings? Is it possible?
So, I'm creating a jungle world that orbits a K class star (aka orange dwarf star), and is the second planet in the system. Now, I have the planet having two moons: one that is similar to our moon (although a bit smaller) and a second moon that is a good bit smaller than that moon. Also, the planet has rings similar to the rings of Saturn/Jupiter.
Now, while countless sources have stated that a two moon system would play havoc on a planet's tidal system, this is taking into account of the amount of ocean that a planet has: it being the same amount as Earth's. (sources that say a two moon system would play havoc on a planet's tidal system and they're the ones that also say that the two moons would eventually collide:

According to this source, http://planetstar.wikia.com/wiki/Forest_planet , jungle and forest planets would hardly have any hurricanes due to their oceans beings not so deep or vast. So, that helps my world a good bit in preventing tidal systems from being extremely dangerous. Plus, the world is only approximately 40% ocean. It still is tectonically active, which helps in creating volcanic eruptions in putting carbon dioxide back into the atmosphere (what with all of the plants on the planet).
Now, while there is a good bit of light coming down to the planet due to the two moons and planetary rings, there would be areas of the planet where hardly any light reaches the forest floor. This is similar to certain rain forests here on Earth (i.e. the Amazon rain forest).
One thing that I looked at was how the planet's gravity would be affected by a two moon system. I figure that it would have a lighter gravity than Earth's, but this would be alright as the two moon's pulling on the planet would probably make it closer to ours, although I'm still researching this, so I could be wrong.
Another factor that I'm looking at is if the planet is a super-Earth. I figure this would also help stabilize tides and make things easier for the dominant species of fox-like caninoids to evolve on the planet.
The thing that I'm worried about is that all of my sources say that the two moons would collide. I've searched and searched but I can't seem to find anything that says how to keep them from colliding with one another.
So basically I'm asking: have I done my homework? Have I forgotten anything? Do I need to look at other sources? What things have I not taken into account when designing this world?
This basically boils down to one question: is this planet even possible?
