1. do you mean flip angle? in resting-state fMRI, we usually use 90 degree. I don't know what's "standard angle".
2. The flip angle in T1 varies in studies and MRI vendors, for our GE MR 750 system, is 8 degree.
3. Do you mean TR in T1 image? It also varies in studies and vendors. As long as your image is right, and your MR technicians says so, you can just report it.
