Yup. Agree on what supercolossal said. But THE most important thing.......
What Amp are you using?
If it's a low-end amp, then don't bother with single effects, it's not going to help much. Since you already have a multi-fx, then you're quite in good hands already. If it's something like the Vox AD series or Marshall AVT, then yeah, it's going to help you out.

Hmmmmmmm....... quite a decent amp there. The biggest thing I read is that the distortion sucks.

Since you already played around with the 707, you'll know what kind of effects you like to use. Overdrive, Distortion, Chorus, blah blah blah.
But the 2 things that Zoom sucks are it's Wah and Distortion/Overdrive. They sound too digital for my taste.

Get a good wah. Tonezone selling the Dunlop GCB-95 for RM480. Good bargain really. If you want more oomph, the Slash Sig wah going for RM780.
You'll also want some warmth in your overdrive. Something tube based like the Vox British Bulldog or EHX English Muffin would be great. But if it's pure metal you want, look no further then the Metal Zone. If you want something even warmer, but want that metal feel, The BEST I've heard is the metal muff.
