to get wifi settings, hit menu button, system settings, then at the top it shows the wifi toggle. well instead of clicking the toggle, click on the words Wifi, then you will be in settings.
as for not getting data, i have a YouTube video found in the OP how to get data going on boot. if the method doesn't work, rebooting into recovery and wiping only cache and dalvik then rebooting system will get your data going. lemme know how it turns out...

Data ended up working thanks to Harmless in the chat room. He told me to wipe cache and dalvik then reboot. And now thanks to you, wifi is up and connected!!!!!!!! Thanks man!
