For ladies I would definitely recommend finding some slightly nicer than normal black flats... I bought some in Prague for super cheap and still wear them all the time!
Definitely worth doing if you are in any way interested in Ancient Rome - the guide is a wealth of knowledge.
If you are doing a time out tour (staying in hotels), a travel iron/hairdryer will come in handy as many european hotels do not provide these facilities.
