Is MultiMC compatible with 1.6 yet? If I recall correctly it is still not. There is supposedly an alpha release of MultiMC5 that might work, but it is still an alpha release and probably will be buggy.
Edit: +1 vote for using the vanilla launcher. Just install forge and copy over the mods folder and the configs and you should be set. Forge has an installer so no more manually editing the minecraft.jar file it does it for you. Look here for DW20's video on that.
