Hi Steve, welcome!
Yes, you should be at least trying to eat all your points. You might need to be planning things out more than you are currently. If you have the occasional day where you plan for blahblah points at dinner and then you are only hungry enough to eat half your dinner, I wouldn't stress about that. But that should be the occasional thing, not the norm.
I had trouble eating all my points in the beginning, and I found the points breakdown in the starting materials super helpful. Looks like in the "Meet PointsPlus 2012" it's on page 56. They have 69 pts a day broken down as: B: 11, L: 20, D: 24, Snack #1: 8, Snack #2: 6, so you would just need to take 1 point off one of those meals to make it 68 daily, plus shuffle things around if you would prefer a little more for certain parts of the day, and just focus on getting each meal or snack close to the suggested breakdown. There's no rush to take off extra points, they will get adjusted down as you lose.
Fuller fat dairy products, salad dressings can help without adding bulk, and nuts/nut butter are also a great way to add points fast without adding too much food. Like 2 Tbsp of peanut butter is 5 pp, and goes well with many things. Slivered almonds with green beans, walnuts over a salad, etc. I had a fat free greek yogurt this morning that was 3 pp for the container but one time I accidentally bought the full fat container - same size - and it was 6 pp for the same amount of yogurt.
You may find that activity helps with the hunger, and it will help your energy levels and mood overall. I did not have much of an appetite when I started WW, especially for breakfast which I almost never ate. Now if someone tried to take my breakfast away I would get all stabby with my fork.

It doesn't have to be taking up running or sitting on an elliptical bored for 30 minutes. Try to make room for what you enjoy. I love being in the water so I started with water aerobics, and I knew I wanted to run someday so I also did some walking on the treadmill. On the weekends I would try to pick out different forest preserves and parks in the area we'd never visited and just walk around the paths there. I found some beautiful places I couldn't believe I had never been to after living in the area for several years. It made activity kind of a little regular weekend project - find undiscovered places to explore.
My husband isn't too heavy but has been pretty inactive and started getting active when I did. He hates running, hates exercise classes, working out at home, etc, but he loves hockey. So instead he took up refresher lessons for ice skating when he started out and now takes hockey classes. Now his routine is weekly hockey classes, some skate time during open skates when he's free, and doing cardio intervals at the gym to work on his endurance - finding something he loved keeps him on track with exercise.
Oh and last thing - make sure you are getting enough sleep when you can. Regular activity can help with that too if that's a problem area. Lack of sleep can really drag your numbers on the scale. You are doing great so far, but it's surprising that these factors completely unrelated to calories you are taking in or burning can also have a profound impact on your loss.
