Hi, as far as I can tell that looks ok, but I'm in 240V-land so things are different here. A photo of the label on the ballast might be helpful as well, I can't read it from what I can see of it. By the way, that lamp needs support, it shouldn't be left hanging from the lampholder like that. I suggest you mount it something like this, which is one of my 35W/55W setups. Mount the lampholder so it's high enough to keep the lamp a quarter of an inch or so above the board, then at the far end of the lamp, put a screw into the board so that it sticks far enough out to support the lamp, which ideally needs to be as close to horizontal as possible. Alternatively, lamps up to 55W can be run vertically CAP UP, but I don't really like doing this unless it's in a fixture that is designed for it.

It depends on what the ballast is rated for. I notice on the label there isn't a temperature marked; our ballasts here have something like "Tw=120°C / 𝚫t=60°C" which means that the maximum temperature the ballast core will stand is 120 degrees C and it should not go higher than 60 degrees above ambient temperature. But without that, it's hard to say. Can you measure the temperature accurately..? I use one of those little laser thermometers, you just aim the laser dot at it and it gives you a reading.
