If you used VGA before you probably had a PC scaler built into the TV. Why not just use that again since it's easier to setup anyway?

I have an HDTV with VGA input and I can choose my resolution no problem (1366x768 at 60Hz) but HDMI won't scale properly nor can I get 60FPS for some reason. I only get 30FPS.

You require either a VGA output, or DVI-I output (with VGA adapter).

As for the "lines" it's not clear to me what you mean.
