For blockoff plates, just pull one of your PAIR tubes off the head and take it to him and have him make plates like the end of the tube.
For the fork brace, have him take the measurements - I'm sure he's got the precision tools, so if he takes the measurements, he'll be able to get every little dimension he needs.
For lowering struts, take one of yours to him and have him make you copies with the holes a little further apart. See the FAQ on making dogbones to get an idea how much further apart the holes should be.
For the motor mounts, it's the two open holes in the lower frame cradle and the hole in the engine just above them. Again, have your machinist friend take his measurements so he knows it's right. Since you're in Canada, you can buy the OEM lower mounts from Suzuki... the CDN 1G B12 had 'em.
A hoseless top end oiler? I haven't seem one of those. Got a picture?
All the ones I've seen use at least one hose.
