That isn't a major problem if you're simply reading the doc, but if you edit it, you'll need something like pdftk to put the separate pages back together. For reading PDFs I've had consistently good results with okular. For "missing font" errors I've found generally that installing the missing font resolves the issue. Run "yum search font" to chase down that possibility. hth.
