Hi all, name is Greg & I have a problem

I'm a 50yr old Kiwi living in Melbourne with my beautiful partner & our 4 yr old ratbag.
Spent to many yrs taking crap photo's then decided i'd had enough of that.
Now i'm trying to learn how to do it properly! So here I am.
Camera is a 400D which i've had for a bit over a year..ditched the kit lens & now have a 28-135 is usm as my stock; though, last month in a moment of madness i bought a 50 1.8II & 430EX & 10-20 sigma which just means i've got more stuff i don't know how to use
