Slime spawn can be fixed rather easily. An old vanilla trick I had was to set up camp in one villiage, dig trenches, trap slimes in the trench, then chop dowm all the houses in the villiage.

Eventually, you end up with only 1 house with your stuff, holes filled with slimes (they have to despawn before they can spawn again outside of the holes) and lots of free farm land.

Downside: Villiagers run off, and don't come back.

Upside: easy to maintain area, no slime problems, and great startup if you survive.

Tekkit side: once you get to EE, you never need to leave your house again. Also, world anchors to keep those pesky slimes in their holes!
