lol'd at "the average world class sprinter"
I have seen a bunch, and there really isn't any meaningful, say, "median". I have seen guys benching 400, and I have seen guys who could barely bench 225, both world-class sprinters.
In terms of power cleans, some sprinters don't even do them, and if they do, they do them with a light weight like 135 because it's convenient.
Having said that, some of the bigger guys I have seen, many of whom were being trained for football and not specifically for sprinting (but who were excellent sprinters), have done power cleans all the way to the floor. I have done them forever, and can still do 225, for about 3 reps like your set. I maxxed out around 250, and the bigger guys (around 200 lbs) were comfortable using 225-250 for several reps.
At your weight, I think that's a great weight to be doing, but I would ask about your form. That's a pretty good weight, and I remember from doing them that the higher the weight went, the lower I could throw the bar before having to sneak under it, to the point where at 250, I felt like it was, for me, too much about sneaking under the bar rather than exploding upwards. Of course, in the most extreme examples like C&J, it's ass-to-grass, with the bar not coming up high at all.
If you aren't getting the bar very high, I would probably back off to around 225, and concentrate on accelerating the bar to a higher velocity, ultimately having it go higher as a result, and not having to sneak under it so deeply.
If I'm wrong and you're getting it nice and high anyway, that compares very well, VERY well, to what I've seen real sprinters do, but there is so much technique and practice involved that without that investment in technique, the weight able to be used isn't really a reflection of sprinting-related ability, it is more just a reflection of clean-related technique.
But heck, if you can do it and do it well, go for it, but make sure you're fresh when you do it.
As for other lifts, we would have to know the purpose of your lifting to suggest anything in addition to the basics you are already doing.
