egalax touchscreen not working

Keyboard being mentioned twice is probably because its got mouse or touch pad as well (seen as an extra input device).
If tinkering with Pi's, its better to connect from your PC to the Pi's BASH command prompt via an SSH client over network as this makes copying and pasting text possible (no need for clumsy pictures of your screen).

That script you mention "https://github.com/brantje/xbian-touch/raw/master/install.sh",
is suppose to do everything for you:
1) Install its own TSlib version (Touch Screen Libraries);
2) Calibrate;
3) Setup "uimapper" that will create another dummy input device with translated coordinates (touch area usually being much larger than the screen resolution so you need something to translate x-y coordinates).

Looks like something went wrong with the script as after running that script, an extra input device should be displayed besides the eGalax one and keyboards when running "evtest" afterwards.
Now "evtest" says "This device is grabbed by another process".
What does "evtest" say when you stop Kodi/XBMC and uimapper ?

Terminal

sudo stop xbmc
sudo stop uimapper
evtest
