woo hoo. Top job.
I've changed more than a few lasers and have had a couple of duff ones so good to hear yours is fine.
The solder blobs are anti static protection during transit. Basically until the laser has the connections plugged onto it there is no ground so if you're charged up and you touch the laser theres a chance that the static on you could damage sensitive parts of it. The solder blobs ensure that any spark it gets don't go anywhere near the sensitive parts.
Regards
