Natural Red to Honey Blonde...HELP!

I have been lurking the board quite a bit and you all are so helpful, I thought I would throw my question out and see if I can get some help and insight.
I am a natural auburn (warm hair and skin) and had virgin hair until a couple weeks ago. My hair got much darker with age and it looked brown. So I got a strawberry blonde (Loreal 7LA) and it did give me more red. Then, I decided I wanted to go lighter but wasn't ready for anything too drastic and started using Sun-In a couple times a week.
My hair is now a more orange color. It's not bad but I am ready to take the plunge.

My goal is a dark honey blonde with darker roots (mild ombré). I don't want to go orange but I do want to keep my red hue. I have been doing a lot of reading and was thinking that I could use an Ash Blonde with a 40 volume developer. I thought that the ash tones would help to diffuse too much brass. I also thought about using a 40 developer with blue anti-brass tint. I am just not sure how to get there...any help would be greatly appreciated. By the way, trial and error is ok but a salon is out of the question. There is just no way.

I cannot post pics so here are some URLs so you can see what I am talking about.

This is my goal color, it is the Scarlett Johanson pic

First off I love the color you are now not many people pull off a brown red but you do so props. You've done good research I think your on the right track. Your really just going to want to watch the color close while processing if it looks like your about right leave it on for just a few min longer and don't get to scared until you blow dry your hair. You may want to use a good toner because of the red in your hair. Redken 8v (or any toner maybe even just try a 8v and a 8a). If your worried about a toner being to strong you can mix a clear gloss equal parts with it to delute it a little bit. Depending on how your hair pulls the 9a with 40 you may not need a toner but better safe than sorry.
Do let us know how it goes and any other questions ill keep an eye out on this thread. Good luck. xoxo

Better pic of current color

Is the bottom part of your hair more of a brown and the top portion more red or is that just the light?

I can't tell if it is just the pic (hard to see irl) but the bottom is kind of ashy greenish yellow...don't dig that.

Ok so, you suggest
1. Lightener and developer ( like the Redken or Scruples)
2. Blue toner - reduce brass
3. Whole head with goal color

Uh hmmm... Sounds good.

THANK YOU SO MUCH! I really appreciate your help! I'll keep you posted.

I am looking online for the products I need but am having a hard time figuring this all out. I found this awesome PDF from Scruples but without the product knowledge, it is hard to figure out what I need and where to get it. I can't pick up the "good stuff" at Sally's. LOL I am sorry to keep on bugging you but can you please give me some more specifics about what and where to buy them. Thank you again.

The Dimensions is a powder Icing is a paste imo Icing is more conditioning that the powder but the powder has a blue tint to it to help pull brassiness. I still prefer Icing over Dimensions.  Being that you have to go lighter than your natural color to get that honey blonde your going to have to lighten anyways so no point is double processing by stipping it then lightening it when the lightner should do just what you need the first time.
I will look up some places to buy this stuff online and post up later today.
