The major crags all withing 30 minutes of Basel are Falkenflue, Pelzli, Gempen, Eptingen, Schauenburgflue, Tüfleten, Bärenfels, Balmchopf, Chuenisberg and Hofstettenchöpfli. Suitable guidebooks are the (above mentioned) Fluebible with the velvet cover and the naked guys, Jura Vertical II and Dreilandrock. All are out of print and very hard to get, since there is no other topo of the region currently available. Jura Plaisir is an option, but it is a selection guidebook that only covers the easier routes. Btw, there are many more crags a bit further away, really a very big set of choices. No problem to climb all year round, shady options for summer, sunny crags for winter.
Mountaineering can be found in the Bernese Oberland, that's about 2 hours away by train. No big deal to get there. Road and Mountain Biking in the hills around Basel are also fantastic. It's a very good place to live for an outdoor enthusiast.
