Hi Jeff, Go for it - you will not regret it. I have had the same boat for 40 years now and find it the perfect way of switching off at weekends (despite a bit of a drain on the wallet and need for diy maintenance!). We have been on the Broads, Thames and currently moored on the River Cam near Cambridge, but our favourite has always been the broads particularly outside the main holiday season.
Not a lot to add to all the good advice already given other than to make sure you have a current marine surveyors report with the boat (This is in addition to a current Boat Safety Certificate). Without this you might struggle to get insurance. You will need insurance to get a Broads Navigation licence.
Personal preference for broads cruising is the Horning, Barton, Stalham area because of a variety of nice weekend trips available. Downside is that this is more expensive than the South Broads and obviously a longer trip for you.
If you ever have an excuse to come over to the Cambridge area give me a shout and we can have a cruise to the local pub and talk boating stuff
