Does anyone have an English copy of Shrodinger's paper "Quantization as an Eigenvalue Problem"?

I've had a terrible time finding it in English. My German in nonexistent. :-)

Having given you the answer you asked for, I would probably direct you away from actually trying to read these papers. They are extremely mathematical; unless you have a thorough grounding in modern quantum theory (at the second or third year graduate level) they're likely to be rather impenetrable.

If you are interested in the background foundations of QM, but are not a physics graduate student, my very first recommendation would be Feynman's QED: The Strange Theory of Light and Matter. It is entirely rigorous, but has no mathematical notation at all. I've read through it many times over the years to remind myself how to explain QM to non-physicists.

If you're more generally interested in the history of modern physics, both Pais and Davies have several very good books out. I also used Williams' The Origins of Field Theory in my undergraduate history of science seminar.

I think this is it:

I'm trying to find it somewhere else though because I don't like their interface, and what's worse is the "download pdf" button isn't working for me
No. The paper the OP is searching for is from Annalen der Physik 1926, entitled, "Quantisation as a problem of characteristic values" (the latter is just the translation of "eigenvalue" into proper English). It's a four-part publication (Ann. Physik 1926, 79:361-376, 79:489-527, 80:437-490, 81:109-139).
From the page numbers you reference,  that's about 140 pages of Physiks, and the document I pointed to is only 22 pages in length. So I guess it's not the same exactly the same thing, or at least not all of it. 
The document you referenced is a different paper, published in the American journal Physical Review; the OP's search is for a series of papers in the German journal Ann. Physik.
The Physical Review article I linked to is some sort of rehash of Ed's original papers published in Ann. Physik. It says so in the introductory paragraph.

"The point of view taken here, which was first published in a series of German papers(2), is rather that material points consist of, or are nothing but, wave systems."

And then the footnote (2) references those articles in Ann. Physiks.

This article is in English, written by Schrodinger, and it's the same topic, and in this sense it is a translation, not a word-for-word translation, but a paper in English on the same topic. 

Also this 22 page article in Physical Review probably does not cover everything that was in the original 140 pages, but that's really blessing though, because most Americans have a short attention-span.
I'm not disagreeing, Jack. It's just that, if you're looking for "history of science" original sources, the PR article is a precis or summary of the original paper, not the true original. It's sort of like taking Eddington's analysis of relativity, instead of Einstein's own 1905 papers.

I suspect that the original poster may find the paper you suggest more approachable, and more useful, than Schrodinger's original tree-murder :-)
Will translation software help you at all?
No, translation software wouldn't help much. These are technical papers in theoretical quantum mechanics (in fact, they are the foundational papers), and the jargon would be unknown to translation software, in either English or German.

I found (via Google Scholar, "Schrodinger 1925 translation") a reference to it, http://www.jstor.org/pss/230015 (footnote 2), which says the papers in English translation may be found in Schrodinger Collected Papers on Wave Mechanics (London: Blackie & Son, 1928).

The latter appears to be available on Amazon as a reprint by
Chelsea, for $36 (hardcover). The original is also available for $138 or more.
