I have a java.util.HashMap object m (a return value from a call to Java code) and I'd like to get a new map with an additional key-value pair.
If m were a Clojure map, I could use:
(assoc m "key" "value")
But trying that on a HashMap gives:
java.lang....

You can.

If I want to learn Clojure, should I start by learning Scheme or Common Lisp?
Or is Clojure different enough from both of these, that I should just start learning Clojure by itself?

The differences between Lisp and Scheme (and Clojure itself for that matter) shouldn't be a concern especially if you are just is best for your needs.
For your purposes I think you are safe to just start learning Clojure.

I am having a hard time writing type checks in Clojure. Pleas help me.
How do I write/perform 'char?' in Clojure? How do I write/perform 'atom?' in Clojure?
How do I know what type an item is in Clojure?
Can I write (type? an-item) ?

Typically type questions in Clojure come down to asking "what class is this, or what primitive-wrapper-class can contain it." This comes from Clojure's first class treatment of java.

What are the most significant differencies between the F# and Clojure ?
Which constructs has F# which Clojure does not have and vice versa?
Does F# have macros?

So F# has a more ML/OCaml/Haskell feel with emphasis on:
static typing type inference pattern... .
Thus is descended from ML while clojure is descended from lisp .
One key difference is that F# is a .NET language, whereas Clojure runs on a JVM.

Clojure is a lisp so learning other lisps will help a lot in getting used to the parts of the "lisp culture" or general way of doign things.
