ok so im new to bp but not reptiles and got a few questions.. id greatly appriciate your help since this seems like a very friendly forum. i got a reptile show on the 13th nd am looking into getting my girl a bp since she has fallin in love with them but am not sure of a few things

1)what should i look for in a hatchling/yearling like size/weight?
2) about what should i pay for say a pinstripe or spider or maby a lesser? or even a bumblebee (pretty sure thats a morph)
3) i have its enclosure set up right now with around a 92 degree hotspot is that to hot? and what should i be trying to get its humidity to?
4)anything else that will help me choose a great pet/possible breeder should i choose to get into that which im not 100% sure i ever will
