You know that part with the lava that you have to cool down with water? The path to Ed is just behind the Flamesword Scale Miners there. Break some stuff and you'll come out to a cliff. There is a lift just to the right that leads to him and allows you to access him within seconds of leaving the 2-1 archstone.

I haven't actually completed 4-2 myself. :P The farming route I use is this: I jump down so that I'm next to the reaper and I kill it. Rinse and repeat.

I found a shortcut that allowed me to skip almost everything in 2-2. Go right at the start, run past all the Scale Miners and you'll come to a hole with a bunch of platforms. Go around it (you can go inbetween the beam/pillars and the wall on the right) and then just jump down, one platform at a time. There are 3 Rockworms at the bottom but you can just sprint past those and run into the exit. This tunnel will lead you directly to the final room before the Flamelurker.

The ring is useful if you have HUGE amounts of ores from farming. The higher quality ores weigh quite a bit, and using the ring will allow you to lengthen farming runs. And btw, you can give all of your ores to Thomas. They'll still be available for use when you go to Ed or Boldwin.
