I think there may be a bug in the new version, in earlier versions you meet Jane on a Saturday, but he changed that in this version, so we may have to wait for a patch.
You find the Sex Shop after witnessing two men and a woman having sex at the bus stop. You then get a new location, Red Light District. From Valerie's apt, take the street to the right, take the old factory, once at the old factory you should see the link for the Red Light district, the sex shop is there.
In the bedroom, click on one of the boxes by the bed, that's Evelyn's stuff.
Barbara should agree to go to the gym. Valerie will ask her boyfriend to join. The barman will also join, but I think only after Alex has a date with him. Once those three join you don't need anyone else. Go to the gym on a Saturday afternoon, and talk to Barbara there. That will start the quest to get Fred to train you.
