I have read through many posts regarding utilization, however I am just not able to grasp exactly how to determine, when to make pmts, etc. Hoping you all will be willing to help me out ... please

I just opened a LOC and used it pay off my CC's, however I just realized from reading here it will appear as a revolving, therefore, I am thinking the raise in score I anticipated may not happen. I have the following:
CC#1 - Limit $500 - Paid down to $0
CC#2 - Limit $500 - Paid down to $24
CC#3 - Limit $500 - Paid down to $25
CC#4 - Limit $600 - Paid down to $0
LOC (recently opened - not yet reported) Limit $8000 - Initial advance $5250
If I am understanding things correctly, I am at about 50% utilization (give or take a few percentage points), is that correct? My last EQ has my debt to credit ratio at 75%. Will going down to 50% help? Or will the combo of high utilization PLUS the newly opened LOC have a negative impact.
I do have a morgage and $36,000 in student loans currently in Forbearance. Your help is appreciated.
