As far as the wizard goes, I couldn't remember much of my time spent leveling 1-25 so i used the leveling guide on the wiki. But the guide past 25 works pretty well also and most of the spots i've actually switched from being for/against etc.
I think around 20 on my wiz i was soloing at the RBF spawn in upper guk till around 24-25.
Starting at around 25ish on your wiz i think the best place is the sisters in oot. Around 29 you can start splitting the 2 spawn in one of the huts (they drop fine steel which sell to the dwarf merchant on that island for about 10pp a pop). As soon as you hit 34 do everything in your power to acquire circle of force, if you still cant find a way to get it contact Tyneestalker in game and I have the runes in my bank and can make you a copy (but i'll charge). Anyhow here is link to said guide:
