iphone app development

I have a start of an iphone app, it reads xml from a website into a table. I would like this table modified to contain 3 columns one with an icon, a textual description and a value. The table also needs to be grouped via the xml. I would also like to touch the row and open a cell in the app which opens a web page, at the moment it opens a new safari window, so just need to add a cell to the view. I also want a logo to appear at the top of a view, I've found this hard as the screen is built via code. I want a loading screen, and to get the xml the user needs to enter some settings, so i need the app changing so that it goes to the settings view rather than display view if they are not set. I would also like a loading view. Not too difficult and half way there. Possibility of more work if this is good. thanks
