Do I need to rescale variables to compare coefficients.

#1
I'm running a regression analysis. My "Y" variable is Yearly_Spend while my "X" variables are Time_Spent (on website in minutes) and Length (of membership in years). Right now my results show Years has a bigger impact on Yearly_Spend. Do get a true apples to apples comparison of the coefficients, does it make sense to rescale my variables and run the analysis again?

Less is more. Stay pure. Stay poor.

If they were standardized then you would have a comparison in regards to a standard deviation increase in either variable, so yes that is what would be done traditionally. You can also report their partial r^2 values.
