Answer 1

why you not using just views?
$view = view_get_view('MY_VIEW_NAME');
$view->set_display('MY_DISPLAY'); // page_1 or block_1 ... block_n, ...page_n
$view->set_items_per_page(0);
$view->execute();
$result = $view->result;
$result will contains array of values of each row

Answer 2

I haven't actually tried this myself. First thing to do would be to execute the views query. This can be done with the execute function.
So doing something like this:
$view->execute('display_id');
Should populate the $view object with at least some data. The data available differs through the different layers of theme functions, so you might not get what you want. But this is the best method I can think of.
