Problems with /spawn and /back

Server is running on Windows Vista x86 with 4 GB of RAM, AMD Athlon 64 X2 dual core 5600+ 2.80 GHz, and Bukkit build is 1.6.4-R0.1. I have ruled out all posibility for Bukkit to be the issue, as it did the same thing during 1.5. My plugin list is ButterBlock, ColoredTexts, CommandBook, CoreProtect 2.07b, DarkBrotherhood v1.7.5, DisguiseCraft, EnderCrystals, Enjin Minecraft Plugin, Essentials, EssentialsChat, Essentials GeoIP, EssentialsGroupBridge, EssentialsSpawn, EssentialsXMPP, Modifyworld, PermissionsEx, PlayerHeads, ProtocolLib-2.4.3, Punishmental, RageBan 2.0.1, Vault, VaultRank, Wabbajack v1.1, WorldEdit, and WorldGuard. When people first log on or die and respawn, they respawn where spawn used to be, long ago, when I was still running vanilla, but if they /spawn, they go to the correct spawn. Also, another plugin conflict I believe is that /back, as defined by Essentials, should take you to your last location, but however when it's done here /back responds with a "-=-You are no longer away.-=-". Also, when someone joins/leaves the game, it no longer says "{name} has joined/left the game". This might be a PEX oversight on my end, though. Every 30 minutes or so, or when someone joins the game, our tags and nicks disappear for several messages and just leaves our names white, as well. This used to not do this before I got ColoredTexts, so if there's a way to change our chat color with things we already have, please let me know. Sorry for this being full of several problems instead of one, but if they're related (as some of them may be) I'd like to get them resolved in one thread.

Thanks!

This post is a big block of text, i suggest splitting up your questions with new lines next time.

"When people first log on or die and respawn, they respawn where spawn used to be, long ago, when I was still running vanilla, but if they /spawn, they go to the correct spawn."
Set /setspawn newbies, newbies being a setting at the bottom of the essentials config.yml

"Also, another plugin conflict I believe is that /back, as defined by Essentials, should take you to your last location, but however when it's done here /back responds with a "-=-You are no longer away.-=-"."
Command is being overridden by the CommandBook plugin, id suggest using either CommandBook or Essentials, since they have a lot of similar functions.

"Also, when someone joins/leaves the game, it no longer says "{name} has joined/left the game"."
Will cover this after other issues are solved.

"This might be a PEX oversight on my end, though. Every 30 minutes or so, or when someone joins the game, our tags and nicks disappear for several messages and just leaves our names white, as well.

You have a few plugins with the same functions. I suggest removing ColoredTexts, as that is mostly covered by Essentials, as well as suggested above, CommandBook.

 

Thanks for replying! Sorry, I was in a bit of a hurry while writing that, I'll try to space it out a bit next time.
One question regarding this-I have some warps set, and have set up PEX to allow Essentials warp commands for ranks, but they aren't able to actually use the commands. If I remove Commandbook, will my warps be gone as well? Just wondering before I delete it and lose my important locations, so if it does I can write down coords and put them back with Essentials. As for ColoredTexts, please tell how to set peoples' chat colors with Essentials.

Thanks again!

**EDIT** I got rid of CommandBook, and reset all my warps where they were, and this has fixed /spawn and /back. I need some people to join and check that our tags don't disappear, but it may have fixed that as well. All that's left to fix is the "{name} has joined/left the game". Thanks so much for your help!
