If you want fast retrieve in order to make more casts, or retrieve certain lures, anything above 6.1:1 is high speed for spinning reels. If that doesn't concern you, there isn't any need to mind the numbers.
The more the bearings, generally the smoother the operation. It all depends on where the bearings are located. For example, a Daiwa Regal, known for being a super smooth 10 bearing reel for only $60, has two stacked bearings on the mainshaft that have no obvious use aside from smoother drag.
However if you get a reel that has 6 or more bearings, you will generally have smooth and quiet operation.
Reel companies sometimes overkill on the max drag. There is absolutley no need for drag heavier than 10-15lb, and even that is way up there. If you lock up a spinning reel at 10lb and the line holds, you're most likely going to break the reel's line roller system or bail. Most of the time, the larger the reel size, the heavier the max drag. On average you will find 10-20 lb max drag.
In terms of line capacity, look to others on that. I do not go out for steelhead often, so simply put make sure you have enough spool size to hold approx 200yd of needed line.
