You just gotta learn how to play with the configuration files. If you want larger keys check out BigKeys on XDA. I made a VGA template of that and if you want to edit it further that is up to you. Just go into the skin files and it is laid out there. If you have questions or want something specific PM me and I will help.
As far as a stable ROM, I just downloaded Calk's Kitchen and made my own with Titanium and the regular phone canvas.

That right there is my selections. Note I'm using an older version of the kitchen but just go through what I've selected and you'll have most of what I have give or take to your preferences.
