Looks real familiar, I've got a similar concept that I'm working on at the moment.
The biggest problem I see is the lack of any kind of mobility post-deployment (I'm not counting the speeders since they'll fall apart under any kind of fire... ). Also, you've got to consider Alpha level missions where you won't be able to infiltrate at all. It's tough to fit everything in a 1500 point list, mine is planned out at 1850 - those extra 350 points really help a lot.
I'm planning on using a Termie squad (with cheapo commander), three infiltrating Las/Plas squads, two infiltrating Dev squads (one 8-man with missile launchers, the other 6-man with Heavy Bolters), an 8-man Assault squad, squad of two Tornadoes, and two 8-man Tacs in Drop Pods decked to the nines. Still light on post-deployment maneuverabillity, but the assault squad and drop pods can at least take a shot at objectives.
You might want to consider putting the Librarian in Termie armor, dropping the command squad and a Terminator, and making the 4 remaining termies into a command squad. That would net you about 130 points. Drop the single speeder to get to 180 points. That's enough for a small, 6-man Assault squad. It's not much, but they'll be more resiliant than the single speeder while being faster than the current command squad.
Good luck, let us know how it works out in the Batreps section!
