For the easier grades, Marin, Toix, Echo Valley 1.5 are all worth a look. Sella is very close to where you'll be staying but the easier stuff is generally polished to hell.
Toix (south facing side) dries very quickly after rain as does Marin.
The Bernia Ridge is an excellent day out. Most of it is about grade 2-3 scrambling but you need a rope for the abseils. There is one bolted section (20m) of around 4/4+ which can be aided if required. The Toix ridge is also fun. The hardest part is the the multi-pitch climb (up to 5/5+) to get on to the ridge. The ridge is just a scramble but with awesome views and crazy exposure.
