I agree with almost all of those. If you do VU though I'd recommend Loaded or their Self-Titled over VU and Nico.
When you said Techno were you just using the generic term people use for a whole bunch of genres? Kind of like Alternative being a wide blanket for all sorts of rock music.
In the "Techno" realm I'd recommend the following.
Amon Tobin - Permutation (Brazillian-born DJ that does a jazzy blend of drum and bass)
DJ Shadow - Endtroducing (Uber-talented turntablist. Just a phenomenal album)
Tricky - Maxinquaye (Trip-Hop, like Massive Attack. Tricky's debut is the only album of his I truly recommend. Everything after tends to be a bit out there)
Fatboy Slim - On the Floor at the Boutique (Rockafeller Skank and Praise You got played to death when they came out and people grew tired of him, but this album is Fatboy Slim doing a live set in Brighton, UK. Very cool continuous mix that puts together a wide set of music)
Propellerheads - Decksanddrumsandrockandroll (They only made one album, but its probably one of my favorites. Most people will know their song Spybreak for being in the Matrix. They do a loungy James Bond-inspired type of drum and bass. Special guest appearances from De La Soul and the Jungle Brothers are standouts)
