what do I need?

[Lee Maschmeyer]

As probably a pretty irrelevant comment:

unzip burnam.zip && unzip wood.zip

might well not do what you want. wood will be unzipped only if burnam 
succeeds. You can both get more reliable results and delay the onset of 
arthritis by doing:

unzip burnam.zip;unzip wood.zip

And of course you can save those knuckles even more by leaving off the .zip 
extensions.

But is this really what you want to do? Unzip extracts everything to the 
current directory unless you use the -d option. If those archives have 
nothing in the root directory then you're OK IF this can be relied on which 
I have no idea. And the `for' loop lets you program around this too; this is 
left as an exercise.
