I was having the bar issue as well on my I760 -- I could never get it to work right so I played around with the xml and I managed to get it to fit in the screen with both top and bottom bars as well as add some new icons for pac-man, scrobble and solitaire.
<attached> is a zip of all the files needed for my customization; which includes the base install and the addition of Opera, HTC Album (much better replacement for pictures), Pac-Man, Scrobble and iContacts.
Just install in the order 01..02..03.. and disable all the today items except for this one.
