A good inktomi listing will not help your looksmart listing and I don't believe it will help you too much with any other of the SE’s (other than ink ones)although there is some talk going around about ink pages that are paid for also being picked up by google but I have doubts about this, for me inktomi is a important SE as it provides search results for quite a few UK based SE's so it's always top of my list very closely followed by Google
Your pages that are in Inktomi are they paid ones? If not that could well be the reason you’re not ranking well, the only page's (free) that do seem to rank well in ink are ones that have been around for age's
Why create a new site just for ink, work on your existing ones try for a title max 5/8 words (keywords 2) description max 20 words (again around 2/3 for the keywords)
You will also need to look at some of the submission services going around I use PT and find them to be very good.
