I had a look at the map and I see you have to cross the Glacier de Chielon. I've not crossed that one, but as a rule of thumb, I'd use a guide to do this, or at least hook up with other people for safety. Some glaciers will have flag markers to set out the safest route to avoid crevasses and don't need special precautions, just good weather. Be careful crossing onto the glacier itself as the edges can be brittle and break when you step on them. The edges can be hard to spot as they can be covered with a lot of scree (loose rock).
At the very minimum I'd want crampons as well as an ice axe - not a short one, they're for vertical ice work, but rather one about 70cm long that is used as a walking stick. Normal walking sticks are a bit too light, but would do in a pinch and it would save you having to carry an axe for the whole trip. Only attempt a glacier crossing if it is "Dry", that is not snow covered, otherwise you will need to be roped up in a team in case someone goes through a snow brige. Wear gaiters as much to protect your legs against scree as snow. At this altitude it can snow at any time of year so be flexible with your timings
Last thing, wear lots of blockout on sunny days. The reflected sunlight and thinner atmosphere makes sunburn particularly bad in the Alps.
Just reading this back it sounds daunting, but it really isn't, just pay attention to conditions and you'll be fine.
