Mainframe Metrics MIPS Forecast

Given the following data sources and their availability:

-=-=-=- Quarterly -=-=-=-
Number of High MIP Users
Number of Med MIP Users
Number of Low MIP Users

Number of MIPS used by all HIGH MIP USERS
Number of MIPS used by all MED MIP USERS
Number of MIPS used by all LOW MIP USERS
(These two together give me the average MIPS used per user, per class)

-=-=-=- Monthly -=-=-=-
Number of Jobs Ran SHORT
Number of Jobs Ran MED
Number of Jobs Ran LONG
(user submitted and regularly scheduled jobs)

-=-=-=- Weekly -=-=-=-
Number of MIPS Used in Production
Number of MIPS Used in Test1
Number of MIPS Used in Test2
Number of MIPS Used in Test3
(What I am trying to forecast sans Production)

-=-=-=- Annually -=-=-=-
Test Schedule Dates

What is the best strategy to do a time series analysis when trying to
forecast the weekly MIPS to use? The only thing I can modifiy in a
planning effort is the Test Schedule and all the data is only for the
Test systems (so I am effectivly blind to the Production metrics
outside of it's MIP usage.)

I am guessing a regression analysis of sorts, comments and suggestions?
