Do you have a Flight Review within the past 24 cal. months? If not you will want to get with a CFI and a flight school and do one, it can be done in a 172 if need be, or if you have someone at your job who is a CFI and they have flown with you maybe you can ask them to give you the endorsement and take care of the ground lesson. Look up 61.56 for the requirements.

Are you still Instrument current? Remember 6 approaches, intercepting, tracking, holding within the preceding 6 cal. months in actual or simulated instrument to keep IFR current, otherwise you get a 6 cal. month to get this done with a safety pilot or CFII, if it's been more than 12 months you'll need an IPC.
