Compare Two Sheets, Copy Data

Hello everyone. I have one for you. Attached are Alert.csv and tracking.xlsx. What I am trying to do are two things.

1 - Alert.csv columns A (First Name), B (Last Name), C (User Email), D (Device Name) and U (OS Name) need to be compared to the data in Tracking.xlsx, and if the data of Alert columns A and B (or C if it's easier) is NOT present in Tracking, then I need Alert columns A, B, C, D and U copied to Tracking columns A, B, C, D and E on the first available row (currently 21).

2 - In Alert.csv, columns F, G, H, I, J, K, L, M, N, O, S and T will contains values of either PASS, FAIL, WARNING or NA. If the values are either FAIL or WARNING I would like the title of that value listed in column X.
For example - Row 16, Preston Soloff has either a warning or fail on: Password, Anti-Spyware, Disk Encryption. So in X16 I would like that cell to read "Password, Anti-Spyware, Disk Encryption".

Is this possible? I would really appreciate any help!
