I can only speak from my own experience with equipment that I can only qualitatively compare with yours.
At the upper end of the range you quote (in the fifties F, 10+ degrees C), you will be warm (unless you are wet). So obviously, it is the lower end of the range that is of concern.
We do our backpacking with a three-season tent, with rainfly; your tent sounds as though it is better in the cold than ours, but possibly not. We camped as low as 4 degrees F, and although it was a horrible night (more later), the tent was not the problem. Assuming your tent is in good condition, it is adequate for your conditions.
On to your sleeping bag. I can't remember if our bags are rated to zero F or to 10 degrees F. Ours are definitely are not rated to below zero, F, but they are warmer than your 32 degree bag. They have always been adequate, although marginal in the 4 degrees F night. One beautiful, clear night we didn't bother setting up the tent, and camped under the stars beside the Tuolumne River. We woke up to find our bags looked like skating rinks. They were covered with icy snow, moisture condensed and frozen on the bags. Our thermometer said the temperature had bottomed at 19 degrees F. We were perfectly warm and comfortable all night. Your sleeping bag is most likely marginal at the lowest of your range, but adequate because you can wear your parka inside the bag. What will make you miserable is damp socks on a cold night. Take one more pair of socks than you think you will need.
Now for the pad. I'm not familiar with the pad you describe, and I don't know the R value of our pads. They are just ensolite pads, not thick, not special, not expensive. They have always been enough, except for that 4 degree F night, and their inadequacy was the source of our misery. However, we were camped on snow -- there was no bare ground anywhere -- and in the early night, heat escaped from our bodies and melted the snow beneath us, which later in the night froze. We were trying to sleep in a narrow, shallow depression of ice that had frozen into the position we occupied during our first period of sleep. The pad would probably have been adequate if there had been no snow, and I think a second pad apiece would have made us far more comfortable.
I'll guess that your pad is adequate except for sleeping on snow.
So your equipment sounds adequate to me, provided you have a parka, dry socks, and warm trousers.
