I have 2 questions.

1. I had some furniture made that has a "Cordova" stain, a very dark
reddish, purplish brown. I haven't been able to replicate that color
with the stains I've been able to find. I think it's possible that I
need to leave the stain on longer to get a darker color, but I'm not
sure.

2. I did a few test pieces with various stains and finishes. With
different products, different woods and different brushes I've gotten
"bubbles".
Is this a known problem?

Finishing is a complex topic, with many books on the topic--much more
information than can reasonably be posted here.

If it's not too far, you may wish to head down to the local public
library's woodworking section. Barring that, a google search online
will give much information on the topic.
