In all honesty:
canon 28-90 1:4-5.6 II - Sell
canon 18-55 1:3.5-5.6 II - Sell
canon 75-300 1:4-5.6 III USM - Sell
canon macro ef-s 60mm 1:2.8usm - Keep
canon 28-135mm 1:3.5-5.6 IS - Sell
Not sure how much you'll get but your overlapping a lot of range and would be better off with less higher quality kit IMO. What to get next all depends on what you want to shoot.
Personally a great kit at a reasonable price would be:
Ultra Wide: Tokina 11-16mm f/2.8, Sigma 10-20 or Canon 10-22
Everyday lens: 18-55 IS or Tamron 17-50 f/2.8, depends on whether you want IS or a larger aperture, if you can afford both check the Canon 17-55 f/2.8 IS. Then again I could be completely wrong and you might love to shoot the 28-135mm as an everyday lens!
Telephoto: Canon 70-200 F4 Non-IS, found at a good price this is a very nice lens, if you don't need IS it should be fantastic at Motor sport events where you can get reasonably close. Also consider the 70-300 IS, doesn't have the build or auto focus but has more reach and IS with a panning mode (I think). for the best of both worlds the 70-200 F4 IS should be a fantastic lens but pricey.
Annoying lens prices have gone through the roof recently.
Oh and I'd take a 40D and better lens any day.
