I used seo elite still do at times. But I don't think there is a special option in any webceo or seoelite that justifies high price for the end user where the user can do all those things manually too.
In my opinion keyword research is the first thing one should do to begin optimisation. I tried WebCEO free trial but to me it looked quite irritating (for keyword research). The best option is google adwords keyword tool for keyword research. Since I am a professional SEO, I couldn't actually make any sense out of this tool. I don't know what people use this application for.
