For the live trap, I would bait it with peanut butter and jelly. Works pretty well and you wont have to worry about catching any cats. For the creek I would preferably use a 1.5 coil spring foohold, but number 1's will work. Find shallow spots with a some what steep high bank and dig a shallow cavity in the side of the bank just above the water level, put the trap about four to five inches out in front of the hole with some kind of lure or bait. If you can find some trails through any thick stuff along the bank of the stream, a snare or 220 conibear works pretty well.
