How can I install it? Can I manually edit that file? If so, what do I change?

Are you using the defalut theme? And do you have other mods installed?
Yes you can intall manually by following information in package-info.xml and copy the files over that need to be.
And to apply the mod edits you would need to open smftrader.xml

Yes I have other mods installed and only using the default theme right now.

Should I install the package even though I'm getting that error and then just modfy the display.template.php file manually, OR should I manually edit all files?

[SMFHacks]

I would install the package and just edit the display.template.php.
The only thing that is added to display.template.php is the number of trades a user has made under their name.
