I will try and give enough detail that you can answer the question...without rambling too much.
Building a cabin/guest house on my 40 acres in central Oklahoma.
I have about 1-2 feet of dirt before you hit rock.
There is a grade...the short sides will be level to each other mostly....long side (front to back) drops about a foot.
I know foundation will be some sort of piers...looking for some advice on what kind of piers....and also the floor framing.
I thought about blocks...but worried about the winds we get in the spring pushing it.
I am in early planning stages.
Thanks in advance...

Have you considered Sonotube forms?

You'll need to drill into the rock and set some anchors that you can tie into the footings. Usually a 3/4" drill bit and a 5/8" bolt with epoxy:

We don't have tubes like that here in Cambodia, unfortunately. What I do here is, form up a column to pour for a footing. Wood is used for the form.
I take the dimensions required for the project, and have flat plates (thickness varies depending on project size) cut slightly smaller than the final exterior dimensions for the columns. I then have pieces of rebar (diameter varies depending on project size) bent into the shape of an "L" and have the long side welded to the bottom of the plates.
After pouring the columns, we insert the plates until they are flush and level with the top of the concrete. We can then weld anything we wish, to those plates.
Below, I will attach a photo of my latest poured column, formed and poured to support a small tower on which to mount antennas, at a height of 7 to 8 meters (~23' to ~26' 3").
The column is 30 cm x 30 cm (~12" x 12") each side, 60 cm (~23.5") deep, and 51 cm x 51 cm (~20" x 20") wide at the base, which is 10 cm (~4") high (thick).
I have no idea if this would, or would not meet "code" in the US, Canada, or elsewhere. Here in Cambodia, they wouldn't know what even "code" is.

Awesome that you are from Cambodia...Part of my business is that I develop donut shops in Texas, Oklahoma, Kansas, Missouri etc...and sell the business. Most of the people that I work with in that way are Cambodian.
Luckily where I live...code is not much of a concern. My county doesnt even have a building inspector. lol.

No. I look like an American. I just live in Cambodia. 
Sorry for the confusion.

You know, I may know a customer of yours, or perhaps, a previous customer. He seems to have done well with donut shops in Texas. He is also a Khmer, who comes and goes from the US, to here in Battambang Province. I don't recall his name at the moment. But, I will get it. That would be a hoot, if we knew someone in common, especially 1/2 a world away from each other.
