Stockholm is the capital of Sweden, as well as the largest city, situated along the south-central east coast of the country. The city itself spreads out quite far into several districts and suburbs, with a large and complex public transportation system.
You can buy tickets for all public transportation via SMS, but this now requires you to pre-register at the SL (Stockholm public transportation) webpage. All other information can be found at http://www.sl.se/en/visitor/tickets/text-me-a-ticket. Observe that if your bus/train is checked by ticket controllers (late weekend nights for metro north of "T-Centralen" there is a very real risk for this), they will check if your ticket was valid when you boarded!
Free-ride.now is an organization with only two prerequisites for admission. Members must pay a monthly fee of about $15 and, as part of a continuous demonstration against metro fares, promise to evade payment every time they ride the metro in Stockholm. If travelers keep their side of the agreement, the group will cover any of the roughly $180 fines that might result of been caught. As an unlimited ride pass for 30 days costs about $120, it is worth the investment if you are in Stockholm for a long period of time. Most strategies appear to involve closely following a fellow traveler, using a scarf or jacket to set off sensors on the far side of the barriers, or simply slipping through the sliding gates.
Hosting community is big enough and finding hosts in the streets does work very well also. Look for people in surrounding cities as well, as the metropolitan area is widespread.
If the weather is good the two parks in downtown, Djurgården (better, calm and isolated on an island) and Ladugårdsgärdet are very good option for camping. Swedish people have a very good respect for camping and won't ever wake you up.
Airport is pretty good place to spend your night. It's quiet, not very busy and has good set of chairs and benches. They have free internet ("Airport-Guest") which you can use for free endlessly if you change your computer mac address every now and then. Only that the shuttle bus/train costs a lot to get there — but if you have a change to get a lift there or use local transport, it's a great place to continue hitchhiking northwards in the morning.

Busking in the old town and the commercial downtown is possible. Choose your place according to your needs. In the old town, there are mainly tourists and people who work with tourists (shopkeepers, street-sellers etc). The roads are narrow and a bit quite. In the commercial area, there are more locals but roads are wider and busier.
If your objective is to find a host or gather a crowd, the second (commercial) option might be better. If you seek to relax, rest, focus on money or meet foreigners, the first (old town) option might be better.
Free lockers can be found at the modern museum. The University provides you with rather cheap coffee, maybe also with free lockers.
