Keef, that's *four* times the power to double the volume...

Keef's recommmendation on using separate guitar and bass amps ain't bad, but everything he warns about can be easily avoided simply by watching the VU meter (or the clipping warning lights on each mixer channel, if the mixer has them).

One significant thing the Wharfedale missing is any kind of foldback. If you haven't got foldback, you can't hear yourself or each other - you can get away without in small places (where the PA sound reflects back off the walls), but in larger places (and especially if you ever play in a marquee) it's essential.

Consider spending as much as you can on the electronics initially - as many channels as you can, with a foldback output. If you're after sound reinforcement in small places initially, small (and cheap) speakers will get you by to start with, and you can upgrade to bigger speakers later. The small speakers will still be useful in future - you can use them for foldback, or you can keep them as an option for use in small upstairs folk clubs. :-) But if you buy a crap mixer to start with, all you'll have when you need to upgrade is a very expensive doorstop and some big (and probably rather average) speakers.
