If you are current in Single Pilot IFR, you won't have any trouble with the Sim. If you're not so current, then you will need to brush up.
Any of the options mentioned above will do. I find doing a couple of approaches on my MS Flight Sim helps to blow away the cobwebs and gets the scan going before my renewals.
Don't be intimidated by the Simulator itself. It's just a big computer on hydraulic jacks!
