stand for? And are they expected to be priced more than an "L"?

I am not sure where I read it. It might have been in the
technology section of the Canon web site or maybe MR’s review
at Luminous Landscape but I know it was suggested that DO would be
a new line of lenses produced by Canon. I guess this technology
was more difficult to perfect than Canon initially thought. I am
sure we will be seeing more DO lenses eventually. From the best I
can tell the reason the price is so high has a lot to do with
difficulties in manufacturing and I am sure because it cost a lot
to develop the tech also.

DO stands for diffractive optics. So far there is only one lens available and it is VERY expensive. You can read all about it on Canon’s web site.

I don't have any "L" lenses yet and I am looking into a couple. I
just started shooting with canon this year and don't know the
history behind it.

If that is the case then why is the 14mm f/2.8L an L lens. It does not have low dispersion glass in it. The 35mm f/1.4L, 85mm f/1.2L and 24mm f/3.5 TS-E don’t have low dispersion glass either. I was wrong about the 400mm DO. I must have misread it the booklet. It has only the DO element and a fluorite element. The MP-E 65mm has a low dispersion element and it is not an L lens. I think that L really does stand for luxury and it pretty much means that the lens uses some high-tech design to achieve better than normal performance.

The L designation came out many years ago with the FD series of lenses. Since then other types of glass have become more common in their lens production such as Flourite. Their first lens being the FL500 which was outside of the original FD breechlock series and long before the EOS series.
