Is there a way to boost the resolution using the SaveAs to get sharper images?
Honestly I don't know. I have not used either as I do most of my work in Acrobat and use O2k... I suppose if there are only these two options and there is no further setting behind the options button, the answer is no...
Will I still be able to open the PDF in Acrobat and attach security levels to prevent modifications, etc.?
Yes, this is not affected by how the PDF was generated.
