Easiest thing to do would be to go into training mode and use the equipment until it is about to break (there are certain counts of course, memorize those counts if you haven't already, I would suggest).
Then, as soon as the equipment is discarded, all you have to do is jump backwards and air dodge or use an aerial (when you're lined up with the equipment of course) to catch it.
For the fire jab, do the same thing, go into training mode and practice the timing, for characters that have different jab variants (i.e. an infinite variant and a standard 3-hit variant), if you slightly pause after doing the 2nd jab and before doing the 3rd, you will perform the single 3rd hit (i.e. Fire jab) as opposed to the Wind jab. In fact, this window to do the single 3rd hit as opposed to the infinite variant can actually be pretty forgiving.
Both'll come, they're just some things that need a little practice.~
