The later versions of Handbrake allow you to select x264's own presets.

Good idea to do a 10 second test, you should do a custom crop to cut off
the bar.

If you have selected strict anamorphic the original aspect ratio is
preserved.

All this info below is specifically about HD only. SD DVDs are more
complicated. If you use strict anamorphic and automatic cropping you
don't have to worry about any of this.

In advanced options put the priority of handbrake on low and just carry
on using your PC.

Typing will not affect Handbrake.

This is SD. S/he has resized the 720 to 1024 to get a 16:9 aspect ratio.
Using anamorphic you keep the 720 width for the encode and expand to 1024
only at playback (saves filesize, bitrate)
