I have absolutely no idea what your budget is... But here goes:
First of all get rid of the mud mixtures. They only heal 1-5, and they do Earth.. Which happens to be blocked by one of the most common shield people carry around.
Blue Scorchstone - A Red Scorchstone isn't good enough for your level of HP. If possible get a Green Scorchstone
Downsize! - Yeah, do what Adam said and get a downsize! to replace with your supersize
Illusen's Earth Potion - Get this...(or you could just get sticky snowballs or something, because this does Earth... and tats a common icon) but if you can afford definately get a Honey Potion
Scroll of Dark Nova - Definately get this.
Lost Desert Dagger - Get one of these
Hand Painted Scarab - Get rid of both of these...
Other than that you would just need a freezer
