Yeah. Not a very informative method, but it can tell you the purity of the DNA/RNA. Absorbances of 1.7-1.9 usually signify purer DNA. You can sometimes use this as a close estimate to the relative amount of DNA, as compared to RNA; however, it is all relative. You can't really base it on this number, especially since cDNA protocols contain a lot of contaminants.
If you can spare some of your sample, run it on a fluorometer. Fluorometers can usually detect small ng amounts of DNA, so you could possibly dilute a small amount (<0.25uL) of your sample.
Sorry I don't know have additional recomendations
