Regarding your second question, the RD will work. You can friction or index a 10-speed cassette with a 9-speed Shimano rear derailer. The shifter controls the speeds and/or indexing; "SIS" derailers (7, 8, 9 speed MTB, 7, 8, 9, 10 speed road) all have the same cable pull ratio and are interchangeable.
I've only tried index for 10-speeds, and I've never tried the Sunrace shifters, so I can't answer your first question. I don't know if the Sunrace shifters have enough travel for a 10 speed cassette. I did notice that the Shimano levers travel farther; 10-speed shifters couldn't reach their 10th click when I mounted them on 9-speed bar-end pods. Shimano's 10-speed bar-end pods are a different casting that allows further lever travel. But, that's for indexing. But, a 10-speed cassette is only ~1.5 mm wider than a 9-speed cassette, so one would hope that the shifters could permit that extra travel. Shimano's 9-speeds did not. Sounds like a definite maybe.
