No idea on the Osmotic Enchanter. I wasted 200 books trying to use the MFR Enchanter to get a Silk Touch book (I finally got it using level 22 on the Enchanter, by the way).
A much better idea, as I've been told, is to enchant gold pickaxes - you'll get Silk Touch about 50% of the time, then use the MFR Disenchanter to create a silk touch book.
For the Efficiency/Speed Upgrade, I collected all the various Efficiency books I got while wasting 200 books to get a Silk Touch.... and I easily combined them all to make two Eff V books for the top tier Quarry Speed Upgrade.
BTW, if you haven't done so, I think a 9x9 Cursed Earth mob farm, with an MFR Auto-Spawner set flush in the middle, is probably the most important thing you can build during early game. It gives access to so many important materials (glowstone from witches, wither skele skulls for making Nether Stars, ender pearls in mass quantity for making Enderium, etc), and of course it provides the Essence to run those MFR Enchanter/Disenchanter machines as well. I don't see how anyone could get thru this modpack without making such a Cursed Earth/Auto-Spawner setup.
