please have a look at 0.9.8-dev
I can't find the file 0.9.8-dev to openssl's home. I found only snapshot. where is dev version files?
in the snapshots (labeled openssl-SNAP-$DATE.tar.gz or use rsync to get a local copy of the cvs repository)
i am interesting /crypto/ec/ec_curve.c is very recently. but, why doe not generation alg open ? (expensive ? patent ? difficult ?)
expensive + difficult and I see no need to do so (don't know if there are any patents in this field)
ecc parametor is hard coding. who supports ecc? if one might want to generate any suitable ecc parametor, like ecdhparamgen command, there are some known algs.
ec parameter generation (i.e. generating a suitable elliptic curve plus generator etc.) is very expensive => one normally uses pre-calculated well-known curves.

I was feeling insecure that same curve have ever been used. whether these curves are secure or not, how to check ?
read textbooks + papers about ecc or trust those who created and verified the ec parameters ;-)
to encrypt needs various module like a rsa n=pq. ecc module is various curve, i think.
no, using the same ec for several ops is more like using the same dsa/dh parameters for more than one signature or key exchange
