ZIP512
when you use low matrix (lower than 256x256), you may use zip512 to increase the display resolution of image.

if the matrix is larger than 256x256, the system automatically use zip512.

help me for looking for some gadolinium product
Linquing,
just saw your thread, and at the same moment this advertisement in another browser:

It seems they are trading gadolinium products around the globe.

ETL for a STIR
I prefer a range from 5-12 (but using shorter TE and TR). High echo trains can lead to blurring, image noise and contrast inhomogeneities.
Parallel imaging can reduce the longer scan time of low ETLs; also often 1 NSA is enough for sufficient SNR.

Hope this helps!

What Philips calls bandwidth
The corresponding term is the water fat shift and can be changed in the contrast parameter table.
Lower bandwidth = higher water fat shift

Omniscan Distribution Rate
I do not doubt that there are small and may be in special cases (perfusion, MRA, etc.) useful differences.
However, I have a lot of practice in MRI and in my opinion, you are right, the differences are small and you can run every type of MRI scans with all conventional Gadolinium containing contrast agents.
