well, if you're going to a studio, first things first, make sure that the drums, guitars, etc are properly tuned before you begin your session. do not overlook this part. garbage in, garbage out. make sure that everythng sounds right BEFORE the engineer hits the record button. if the studio has an iso booth it would better to put the guitar amp in there so as to minimize the bleed that goes into the drum mics. these days instruments can be recorded in full bandwidth thanks to digital technology, and then mixed afterwards. it would be good if you can do vocal overdubs as the most important part of a song are the vocals (if a song has vocals, that is). therefore, it has to be perfect. this is where curing or punching in can help big time, aside from the isolation a vocal overdub provides (which makes mixing easier). from what i hear this is how the first bamboo album was done. everything was recorded live in a small room, then bamboo overdubbed his vocal parts later. good luck.
