What are your reservations about the Paramount for longer distance? If there's something that doesn't work quite right, absolutely, get it fixed. Better, learn to work on the bike yourself if you haven't already. Older bikes are easier to work on, I think. Get the fit just right- saddle position, stem height & length, bars. Slightly bigger tires (like 700x25) will give more cushion. Sturdy wheels will help, too. The one thing I can think of that you might upgrade or need a new bike for is lower gearing for big hills.
