Pennames and Titles

I've already decided on my pen name. I was thinking of using just my regular name but decided against it for some reason which I can't remember. My pen name is going to be...

T.A. Stone
Why did I choose T.A. Stone? The first two initials are actually mine, and Stone is my mom's maiden name. I was thinking 'Nicole' or 'Beth' or something, but they really just have nothing similar to me at all except for the fact that on my blogs that's what I go by. And with Nicole there's no reason I would choose it.
Anyways, what do you think about it? Is it really nice, or is it really bad? Is it just in the middle? I really want to know what the readers think, so that I can build on the common viewpoint.

Building on that, I want to know what you think of the titles. 'Escape!' really actually fits the book, but does it sound like a good book? Should I continue with the title, or change it (again)? Same with 'Trapped' (which is no longer the series title but now the first book's title) and The Fifth Element.
They all fit (actually, I don't know about Trapped), so that's not what I'm worried about. I'm worried about whether they're actually good titles. Would you read any book like mine with that particular title?
Series names are hard too. I really just can't write stories that aren't series, it is really hard for me to just end it. 'Chosen' is probably the simplest, but also the one that fits best. 'The Final Drakkon Reborn' always works for me. Again, are they something that are eye catching? If you'll just post this one time, it'll save me tons of time. And time is money.
