I think the meeting of the GL's would have been interesting, but we will never know. As for Jar Jar, I think the criticism of him has been overblown since the beginning. I think of him as a big dumb Ewok with ears, period. Did it make TPM more kid friendily? Sure, but I think the fact TPM is in an era of Star Wars history where things were the happiest and/or most peaceful before the Clone Wars and Empire, I therefore don't find it that bad. Just my two cents.
