How to reverse-engineer / decompile an Android APK which was obfuscated using ProGuard?

Unfortunately, I have lost the source code of one of my apps which I obfuscated using ProGuard.
I still have the .apk file and some config files which were generated by ProGuard:

1. dump.txt
2. mapping.txt
3. seeds.txt
4. usage.txt

What have I done so far?

1. Decoded resource files using apktool.
   Yay, I've got those back!

2. Extracted .apk file and converted the classes.dex file into a .jar file using dex2jar.

If I now view the source code (.jar file) using JD-Gui, I see my obfuscated code. Something like this:

class c {
  TextView a;
  TextView b;
  TextView c;
  TextView d;
  CheckBox e;
}

protected List a(Uri[] paramArrayOfUri) { ... }

protected void a(List paramList) { ... }

Also some loops look a bit weird. I don't write infinite loops:

while (true) {
     if (!localIterator.hasNext())
        return localArrayList;
     ProviderInfo[] arrayOfProviderInfo = ((PackageInfo)localIterator.next()).providers;
     if (arrayOfProviderInfo == null)
        continue;
     int i = arrayOfProviderInfo.length;
}

Is it possible to re-map the obfuscated code to my original source code using any of ProGuard's .txt files? I would like to see my own variable names / method signatures.
Or can these files only be used to follow crash report stack traces?
