1) that blob list is a common to more than one device, so your device
may have even more blobs.
2) I've looked at that blob list, and the most problematic thing seems
the firmwares:

You should find out what are theses firmwares supposed to do before
starting.
For instance the nexus one cound't have sound without some firmwares,
which made it very very bad.
3) That qualcomm system on a chip most probably has shared memory
between the modem and the CPU, which makes it bad for freedom.
4) Some comments on the blobs:
* Audio libs will need to be replaced, that's probably doable.
* The modem is probably doable easily thanks to libqmi[1].
* I've no idea what Thermald is
* I've no idea about the difficulty of replacing the sensors
library, to get an idea, you should look at which exact chip you
have: some akm chips have a replaced free software library(like
for the nexus one), and some don't (like the htc dream) because it
was too hard.
* The GPS may be doable, there was some free software code for it
for the nexus one.
* As for the rest of the replicant devices, there is still the "wifi
firmwares issue"
PS: Next time, send that kind of mail trough the replicant mailing
list. I've put the mailing list in Cc so theses infos don't get lost.
