Default [Q] Lack of useful info

I've spent the better part of 4 days trying to simply get my GNEX back to a use able state so I could potentially flash the kit kat 4.4 rom on it, I have gone back to the wugfresh root tool box and performed that procedure 4 times and I get two of the same issues every time.. Super SU binaries won't update and play store wont connect. From what I've read the Super su could be stopping the play store from connecting. But on at least two occasions I didn't even have the Icon. I came on here and asked Nitro about it. He said I just needed to flash a rom and gapps. but the phone won't show them when I'm in recovery. I find it hard to believe this is turning out to be so impossible. Is there any particular ROM and GAPPS someone would suggest. Most answers on these forums make the word vague look vague. I'm just shocked that with all the talent here no one can help me!
