Moving form Blogger to my new Atahulapa WP site

I've got a few questions for you guys - hopefully someone can give me some in depth answers that are still simple to understand, as I'm still new to WP.

Firstly, I'm currently building a new blog using the most recent version of Atahulapa (www.unbecomingmymother.com) and once I have everything the way I want it (I'm almost there!) I'd like to copy the settings over to use on my other blog which is currently on a temporary URL because the main URL (www.madewithpink.com) is hosted with Blogger.

So, a few questions:

1. Although my blog is hosted by Blogger I invested in my own custom domain upfront, so my URL has always been http://www.madewithpink.com and I intend to keep it that way once I move. Can anyone tell me if I will have any link issues when I move my blog over to WordPress given that the domain name will be the same, but hosted with host gator rather than blogger?

2. I am in the process of designing a second totally different blog on WordPress. I had intended to get the blog layout and design customised the way I like, and then copy the theme settings over to my dummy URL where I would then update the colour scheme & layout a bit more before then transferring my Made With Pink blog to the newley designed one in WordPress. I am using the Athualapha theme.

Can you tell me if this is the right order I should be doing things in? Basically I had planned in having the site layout & pluggina & widgets fully designed before transferring over the content. Is this a good idea? I’m new to the Athualapha theme I’m using, so don’t know if it effects the transfer at all?

3. One last thing – about 95% of my images on my blog are hosted through Flickr and are inserted into the post via URL links. Is this a problem?

I would really appreciate any advice that you might have, as this is something I’ve wanted to do for 2 years but have been too scared to so it on my own!

Sorry this was so long, but thanks very much for taking the time to read it!
