The big thing about Orlando when it comes to where you want to live is not so much the traffic, but the toll roads which can be a bit pricey. That's why people generally live closer to where they work, to avoid the tolls. I believe you can get from any place to any place without hitting the tolls, it will just take a lot longer.
The Apopka area is actually pretty nice and when you get closer to Clermont you're looking at a place that is quite hilly.
As far as golf courses go, the big thing you'll want is not only a nice course, but a place where the practice facility is open a bit late. A lot of these places will close down right at 3pm or so. I just know from experience that is something you want to look out for.
I also would not want to pay a lot for membership. The courses need you more than you need them. Come April thru December, you can get on so many great courses for such a cheap rate. I am a member at one course almost exclusively for the range membership. It's a good course, but extremely difficult and when the wind is blowing it isn't a lot of fun. So I often end up playing somewhere else with my dad on the weekends for rates that will blow your mind on GolfNow.
Also, be prepared to get hammered on vehicle registration. Something like $600 a car. I did a double-take on that and the DMV lady thought *I* was nuts for asking the price again.
Good golf courses around Apopka are:
RedTail (about 20 mins)
Deer Island (about 30 mins)
Mission Inn - El Campeon (about 30 mins)
Metrowest (about 25 mins)
Tuscawilla CC (about 35 mins)
Legacy Club at Alaqua Lakes (about 25 mins)
Timacuan Golf Club (about 30 mins)
If you're looking at Barrington, I think Legacy Club at Alaqua Lakes is a great place for a membership. Not sure what you can afford, but you'll be saving a lot more money if you're making the same $$$ and moving from NJ to here. Cost of living is about 15% cheaper and no state income tax.
You'll get used the summers in about 3 years. The fall, winters and early spring will be a huge relief. And when it comes to Florida, it's selling point is recreation. All sorts of people doing all sorts of recreation every day, especially after work.
