i dont care for the JP video all that much and i really hate michael angelo.
if you want to build your chops, do the 10-hour workout by vai (do a forum search for it and you should find it somehow, its also in this section of the forum on pg 3 or 4 i forget). that should get your accuracy better, other than that, id suggest
paul gilbert's terrifying rock guitar series,
jason becker's series or even yngwie's videos if you can stomach an hour of yngwie.
another totally kick ass video is al dimeola's REH video, you want to build your chops, and have a ton of time, id go with that. Danny Gatton has a cool Hot Licks video too, i dunno if country would be ur thing, gatton was a god and everyone should bask in his wisdom (such a shame...

)
hope this was helpful
