Allright, time to respond to this one.

If we toss all or crap and trash into the sun our planet will become less and less dense (granted by only a microscopic amount).
But you're failing to realize that every day, the sun bombards the earth with solar particles. These particles enter our atmosphere and burn up.
As do meteors.
So they enter as matter, and are immediately converted to energy. Which through your logic will at some point be converted back to matter.
And asteroids certainly add direct mass to the planet.
Add this to the fact that we have 2785 satellites, 95 space probes, and 6163 pieces of earth-originated debris orbiting the planet. And this doesn't account for planetary exploration, universal exploration, and items lost from orbit. The lack of mass arguement quickly loses weight (bad pun, I know.).

Also the areas of landfill become valuable real estate when the landfill is full. It also provides for a great source of fertilizers, natural resources once again returned to the land, and a possible alternate fuel source (methane).
Some areas do become valuable real estate. However, this is outside the norm. "Converted" landfill only gets developed out of necessity, and only where property values are astronomical.
The amount of methane released from a medium sized landfill is minimal at best. I read an article where a school struck an agreement with a landfill to purchase all released methane. They used it to
supplement their energy usage, not replace it.

The only problem is guaranteeing the overweight rocket can leave Earth's atmosphere and go far enough so as to not reenter our orbit.
We've nearly perfected this. The beauty of it is that if it does not make it, there are 3 possibilities:
1. It explodes upon takeoff, effectively creating an "accidental incinerator".
2. It explodes while still within the earth's atmosphere, dumping what doesn't incinerate into the ocean. No problem there. We, and plenty of other nations, already dump raw trash into the ocean.
3. It makes it out of the atmosphere and gets stuck in our orbit. Two options here. Either shoot it back towards earth so it can burn up, or send it out towards the sun.
