I have a one year old site that has about 1/2 of the files (PDFs) no indexed. I just started shooting up the ranking about a month ago as people really strarted to talk and link to the site.
I haven't had a problem at all with it. Ranks keep going up.
No index was a real concern for me, but so far so good.
