I would not use insomina for Technomancers. Yes, it sounds like it should fit, however insomnia is "You suck at healing." Especially with so low intuition and will power. Its something you really do not want to do with an archetype that is so likely to take damage from just about everything.
For a Mancer, What I've found is you want as much willpower as you can possible hold. Its used in every single defense test on the matrix pretty much. Its used to resist damage on the matrix, from fade, and helps with healing, as well as addiction tests. And you can even just use up your one turn in combat if need be to go full defense even in the meatworld, getting a bunch more dice.
About addiction tests, Big reason i bring this up, is that Technomancers can easily use drugs as a sort of "program" they can load. I'd take a look at datatrails too. There is a thing there called garbage in garbage out, that is very good when combined with long hacking, and long hall +cleaner could allow you to do this long hacking for three days straight.
Something a lot of my Technos are starting to use now is pistol with capsule rounds and something like pepper punch or neruostun + dmso, as a means of recovering their more crappy physical abilities, but having something that just needs to have a grazing hit and packs a big punch.
