Hitchwiki states that there are very few checks on trams, but there's no way to avoid it when it happens, therefore it's better to have a ticket you can validate on the go when you see them.

A good place to sleep is Parc aux Angeliques. If you go far enough along the river from south to north, there will be a lot of good places to sleep with or without a tent. Fye checked the place 08.2017. There were pretty much of nomad-like people already sleeping or even living there. It's not too much though and not a hobo like/dirty place. It's just enough to feel safe. The place is quiet enough to feel safe even if you were alone there. In the daytime there are many people making picnics, general atmosphere is friendly. Slept close to the bar/restaurant called ALRIQ. The staff is friendly and even offered to refill a bottle with ice cold fresh water from a special tap near the bar instead of a toilet sink. There was a free concert in the evening there. There is also a free public toilet nearby. You have nice views to the river and it's possible to sleep on the shore.
Burger King on the corner of Cours Victor Hugo and Rue Sainte-Catherine is open till 2:00 am on weekends and there are power sockets to charge as well. There is a bar/restaurant/coffee shop in the same Parc aux Angeliques called Darwin which has passwordless wifi (08.2017) and there is a lot of space outside to sit, even if you won't buy anything staff probably won't bother you.
One of the best cities ever busked in. Made around 30 euro for 2h of playing in Rue des Remparts on a Saturday evening. Even more important, people were friendly and often stopped to listen.
