You'll gain almost all of your muscle/strength from your strength training.
Rowing will improve your cardiovascular system and burn some calories. Unless you do 20 second all-out sprints, you're not pulliing hard enough to build muscle.
I think that depends upon your starting point. As someone who has not done strength training for 35 years I have definitely increased muscle when rowing, but will never have a heavily muscled body as a result. Conventional wisdom is that you can't lose fat without losing some muscle. Indeed body builders cycle through bulking up and losing weight. That said, exercising during weight loss will reduce the muscle loss and losing the fat will make the remaining muscle more visible.
Well done on making a start on the weight loss and the volume of work done.
As for what you are doing, you may find that slowing the recovery between strokes enables you to get more power in the stroke. Done properly you should be pushing hard during the drive and then allowing your muscles to recover before the next drive. For regular training of 10k most of us do 22 or less strokes a minute not 30. As a result the effort during the drive is much higher than more continuous exercises and has been variously compared to a horizontal squat or dead lift. The aim is to go back with a smooth acceleration of the handle much quicker than the gentle slide back to the catch. You may be losing power particularly if the initial leg drive is not matched by the handle accelerating at the same speed. This is often because the catch is taken with bent arms (so legs initially straighten the arms), hands are too low at the catch (initial drive lifts up the chain) or you are in a weak position at the catch and rock forward (legs rocking you over).
I suggest you pay some attention o the "work per stroke". Divide the watts by the stroke rate. So 10k in 55min averages 83W so @ 30SPM, 2.8WMin (168J). A 1m squat would be 134 x 9.8 x 1 = 1313J ( 21.9WMin). While you would not expect to maintain the same power as a squat for a 10k, I suspect that you could readily double your current work per stroke. At 18SPM double your current work per stroke would be 2.8 x 2 x 18 = 101W or about 2:30 per 500m (50min 10k). It does depend how long your stroke is, but at present I suspect that more of your energy is going into [propelling your weight up and down the rail than pulling the handle and so it is not recorded by the machine. As the energy required to go up and down the slide increases with the cube of the rating, this will be greatly reduced at lower ratings leaving you with the capacity to use the energy to accelerate the handle. For now I suggest concentrating on pulling strong strokes with a slow recovery rather than the overall pace. Get teh stroke right and greater speed will follow.
