Hello,
As to table lines, the converter will not remove lines, but it will not repeat lines either. This means if you use border-collapse to create a single line between row A and row B and a page break occurs between these two rows, then that line will be either at the bottom of the first page or at the top of second page. It won't be on both pages. If this visually creates a problem for you, you can try to compensate it with table header/footer repeating feature:

Blurring should not be an issue if you use SVG based chart. We have very good SVG rendering result. Most modern chart library uses SVG since it can be scaled in infinitely without losing quality.
You can easily add a page number at the bottom of the page. There are a number of ways to do so. See here for more details:
