Paracetamol for the temperature. And plenty of water.

For the throat, um, I haven't tried this, but someone I used to work with absolutely swore by gargling with Aspro Clear. Difflam (lozenges that have some kind of magical numbing mojo) is good too, for certain kinds of sore throats anyway (they never could compete with my tonsilitis though).

Oh, and red wine always helps me, but I suppose that doesn't really help when you need to go to work...
