If you're looking at the wholesale lots at CI, those are some very good prices for bulk coins, but not sure if you're going to find much success in trying to resell them in any context other than coin shows. eBay is a wasteland for coin sales, and the work that goes into catalouging individual units out of bulk buys is the reason why deals like the ones at CI are available.
If you go for the deal, just from personal experience with coins, coin shows and eBay, I'd say go for the first one -- as high a quantity as you can afford -- and group them as small wholesale lots online. Your profit margins as a % will be small, but per-order profit will be enough to justify the effort, and you might get some very nice coins out of the deal.
There's a dealer in Pennsyvania whose name escapes me but will try to look them up. They have some very nice wholesale plans that cost some money to get into, but have top-notch products and they will take back any part of a given shipment that doesn't meet expectation. They're often in Coin Price with a full- or two-page ad inside the cover.
