I don't let any of the hoses go past 150,000 miles, but that only take me 6 years to do, so you're probably okay on those items for a little while longer. The tell-tale sign on those is the plastic connectors starting to look brown instead of black. I'd be most concerned with the age of your expansion tank.
You're 100% on with the OFHG situation - definitely easiest and most labor saving to do cooling system hoses, CCV and OFHG at the same time.

Yeah I'm at 5 years of ownership as of next month and I think he did the cooling hoses/system about a year or two prior - so I might be hitting the age threshold and not necessarily the mileage threshold (my miles are still super low at 90k)
How long until you did the OFHG? I didn't notice any leaks when I did my CCV in June of 2014, but will check it out again.
I just ordered INA idler pulley and tensioner pulley and a set of conti belts so it will give me a good opportunity to really inspect the tank, hoses, and spin the water pump and listen for noises - if anything needs addressing I'll just leave it open and get the parts -
