Of all things, bearings have to be one of the hardest things to diagnose over the internet. You've made a few posts on this subject looking for info. You're going to have be prepared to have someone either come check out your engine, and/or find an engine machine shop to do the work.
If you have either a spun or worn rod bearing or a main journal bearing, you'll need to either replace the crankshaft or have it machined and hardened. You'll also need to measure all the journals to source correct size bearings, not to mention having to use Plasti-Gauge on all of them to ensure correct tolerances. You may need to replace a connecting rod if you spun a bearing.
Of all things on an engine, bearings require precision and cleanliness with a close eye for detail and proceedures. This is not something you're going to do in your driveway.
Sorry it'* not easier than this, if in fact it is even bearing trouble you're experiencing.
Cheers,

Yea, its very important to be precise with bearings, most bottom end work I leave up to the machinist to order bearings for because its very important to keep within the manufactors tolerence spec. You should just take the engine out strip it down to the block and take it to the machine shop and do a lowerend rebuild, or thats what Id do, well what I did was just replaced the engine... But you get the point.
