Answer 1

Both LWUIT & j2me polish provide good GUI facility which was once missed in j2me. Both supports 500+ different phones models, as it will face in real market. My opinion is to use LWUIT, sun is giving lot more support for the LWUIT. J2ME Polish is has lesser chance in covering most number of handsets in the market. You can also have a look on this and this thread. They have some discussion about LWUIT vs. J2ME Polish.

Answer 2

Both of the links from Abdullah are somewhat outdated. Effectively both LWUIT & AFAIK J2ME Polish are effectively dead end technologies (disclaimer I'm one of the founders of LWUIT).

Both take radically different approaches: LWUIT tries to unify all devices while Polish uses Macros to workaround the differences.

Since both Chen and myself left Sun/Oracle and no longer maintain LWUIT it probably won't see significant progress or support. We are now developing Codename One which has LWUIT roots but goes much further. However, if your only target is older J2ME devices/networks that might not be the best direction for you.
