Ciao emiazz,
I'm from just outside glasgow, so I will try my best to help. Most places in glasgow city centre are absolutely fine to live in, however some area in tradeston, the gorbals, and dennistoun can be a bit dodgy. However having said that the new devlepments in these areas are fine. Most of the west end of glasgow near glasgow uni (kelvinbridge, kelvingrove, kelvinside etc) are absolutley fine to live in aswell. The only areas in the westend that again can be quite dodgy in some areas are, maryhill, some parts of anniesland. The south side of glasgow is in the most part really nice, and is fairly cheaper to stay than the west end and city centre, but is still quite safe. There are some area of the southdside that are still quite rough, however langside, shawlands, mount florida etc are fantastic places to live. Warning though stay away from tory glen!!!!! I would personnaly recommend the south side as it is very much an upcoming place in glasgow and there are lots of students there.
I would advise you to stay well away from anywhere in the east end of glasgow because although there are one or two nice places, for the most part it is rough. And by rough I mean napoli rough! Again north glasgow can be ok, but it's not really for students.
My advice would be to find somewhere in the west end, preferably near glasgow uni, in the city centre (avoiding tradeston, anywhere past trongate, some parts of denniston and the old parts of the gorbals), or the south side, stick to the shawlands, langside, mount florida area. These generally are the areas most students stay in anyway.
Also if you want, you could always try and get student accomodation in one of the private student halls, which are mainly in the merchant city (city centre). Here's the link:

All ranging from lecce, bari (where my father comes from) to Bergamo and Milan. There is an abundance of italian restaurants (although only a few cook italian food the way you are used to). So don't worry about feeling like a stranger or feel that the locals will be intimidated by you, because they are more than used to italians by now, and have grown to love the italian community.
I would also like to point out that you should prepare yourself for a total change in the quality of food you are used to. Scotland has good cusine don't get me wrong, but the food most of the supermarkets and to some extent the restaurants sell will not be to your standard, especially the italian food shops sell. A small tip, don't buy pizza from pizza hut, dominoes or papa johns, they are not what an italian would call pizza. If you would like a proper authentic pizza try and find a good italian pizzeria, I would recomend the italian kitchen on ingram street and the mediterraneo on ingram street, they both have stone bake ovens and italian pizza chefs.
Anyway, good luck on finding a place to stay and if you want to ask anymore question, quote this or PM me.
EDIT: I also forgot to mention if you are thinking about living outside glasgow, then don't live in south lanarkshire. I come from south lanarkshire, and I can assure you, it is not a place you want to stay lol.
