Maybe it's just me (and even if it's not, I don't give a rip. "Old" is like that

) but firstly, I think speed is overrated. I used to play real fast stuff, but now, I've moved away from it in favor of tone and phrasing. Blinding speed is only acceptable when it's done super clean. When it's sloppy, it's a total waste of time. Here my take, in order of priority:
1. Playing the right notes (do ray mi)
2. Playing them clean (articulation)
3. Timing and rhythm (one, two, three. four)
4. Tone (nice sounding)
5. Phrasing (Adding the "Oooo dat's nice" factor)
6. Vibrato and other "finishing techniques
7. Yada-yada
8. Yada-yada
9. Speed
10. Hat
11. Sunglasses
12. Effects
Until you get your timing and rhythm nailed down, you're not making music, AND it just may even turn out to be your biggest challenge.
