Run Profiler, Execution Plan.....on Package

I want to run a Profile and/or Execution PLan on my Package to see where the most resources are being used when I run my process. I am using SQL Developer and have been reading about different ways to do this but would like to know an easy way to just see what my procedure(in my package) is looking like as far as Table Scans, Reads, etc.. and maybe what I can do to help optimize what I have now before I go and redo this a more efficient way. We will be using this for now and when I have some down time I will come back and rewrite it, using some experts advice, and get it to run more efficiently.
I just need to be able to see how its doing via a Profile and/or an Execution plan now to see what I can do ? Also, if your real good at these types of thing you can tell me what to look for when I actually get the Plan back? Or I can look that part up ;)

Thanks
