git merge after git cherry-pick?

Hi,

Still being a newbie...

On a branch, b, made off of master, I've made the commits b1, b2, b3 and 
b4.

Back on master, I need commit b1 and b3 immediately. So I:

$ git checkout master
$ git cherry-pick "b1's SHA"
$ git cherry-pick "b3's SHA"

Now, both b and master contain b1 and b3. How do I now create a log of 
"what remains to be merged from b to master", i.e. only b2 and b4? And 
how do I merge b2 and b4 to master, so master's log shows b1, b3, b2 and 
b4 and doesn't show b1 and b3 twice, which is what I get if I:

$ git merge b

after the cherry-picks above. Also I noticed, that if I merge master 
into b (to keep up-to-date with master) b1 and b3 are also mentioned twice.

I did notice that cherry-pick created new SHA1 IDs for the commits for 
b1 and b3 on master (as indeed man cherry-pick also says). Maybe 
cherry-pick is not the right tool for the job. Is there another way to 
"copy"/"merge" only b1 and b3 (but not b2 and b4) from b into master 
maintaining merge history and avoiding them being mentioned twice later?

At the time of writing b1-b4, I did not know that b1 and b3 would be 
needed separately, so I didn't put (b1 and b3) and (b2 and b4) on 
separate branches. I did notice though, that they weren't an intricate 
part of "the new feature". Is it required that I then do the work in 
separate branches?

I hope this is possible as I'm thrilled with git!

Peter
