Removed unity have i3, is a bit quirky and need help tidying.

I had a choice of unity and i3 at the lightdm login, once I was used to i3 I decided to remove unity- this wasn't so much because I didn't want both, that was a good setup, I removed it because
there is a handful of quirky config conflicts and I couldn't customize i3, these issues were:

A grey menu bar for each newly created and stacked i3 terminal.
That really quite nice deep purple background.
the better ubuntu font.
that i3 config would not change the font type.

also I wouldlike to know how to auto start i3 with light dm, as I have started differently a lot of the walkthroughs and tutorials I find simply dont apply to my situation,
lightdm never has the config file its suppoed to, i3 doesnt have the fonts folder, where are these things?

Also, I did use that menu bar to select preferences and have it never show up again, I also used it to change to a font htat I have gone off, ironically know that aoying menu bar HAS gone, I cant change the font back.

Incidently there is some use to the old ubuntu stuff, if I get could the networking gui upp, it was easy to conenct to wifi than with network manager.
and the old profile preferences, is there a commond shortcut to get that up too? after all I just told the menu not to appear I didn't delete it

It seems there's accidental problems but everythings still sort of working nicely and I could put up with the conflict if I could solve these specific issues.

-if I could get profile preferences up can someone tell me how to add a new font-

I can see this post is messy with lots of bits on it but ultimatley im looking for a bit of direction.
