[Droid Eris Q&A, Help & Troubleshooting] KarateExplosion6:
I don't know what to tell you, as removing stock applications with zach.xtr's Gscript process has always worked flawlessly for me. You may want to upgrade to the new xtrSENSE4.6 Beta that is out (you can find it by browser the more recent posts at the end of the xtrSENSE thread--Zach posted a link).

All I can say is that, when using Gscripts, make sure that you have "Needs SU?" checked. Aside from that, you just need to load Zach's scripts into Gscripts. After you load the scripts, have you pressed them? Just because you've loaded them into Gscripts doesn't mean they've run. You actually need to press on them to run them.

I've used all of them at various points in time--I used to use A2SD and C2SD, but ever since C2C was developed I've had no need. In xtrSENSE4.2, I'm pretty sure C2C is enabled by default. So, you don't need to worry about it UNLESS you're running low on disk space. If you're running low, how many apps do you have installed (you should be able to store ~100 with C2C)?

My recommendation would be NOT to use SetCPU. I've found that running both of Zach's Gscripts for Max and Min CPU Speed has worked better--you won't need to wait for SetCPU to load up, be granted Superuser Permission, and then adjust your clock settings on boot. Plus, you'll have one less process running at all times, increasing performance.

Additionally, you may want to take a look at the xtrSENSE4.6 Beta that I mentioned previously. New, in that version, is the first ever inclusion of Collins_ph's Battery Tweak. Previously, it could only be used with Froyo ROMs. Enabling and configuring the utility will increase battery life because it gradually turns down the speed on your processor proportionally as your battery drains.

In terms of making the ROM "your own," I'd take a look in the Theme's thread. I can't provide you a list of everything that will work on xtrSENSE, but I can confirm that both the Minimal Matte Grey and Touch of Legend MetaMorph Themes do work for xtrSENSE. Also, you may want to check out LauncherPro (Plus), if you haven't already (www.launcherpro.com)... I absolutely love LauncherPro Plus, but I'm not "actively" using it. I'm really waiting on Fede to develop acceptable Photo and Music widgets to replace HTC's Sense Widgets (if anyone has suggestions on existing replacements, please let me know...). Having said that, I run a secondary "experimental" ROM on weekend--I run xtrROM with LauncherPro Plus. If you do decide to use LauncherPro, then I'd really recommend taking a look at xtrROM verses xtrSENSE.

Also, if you're a Sense fan, you might want to check out the newest version of KaosLegendary, V18. This is a port of a Tiawanese leaked version of HTC's forecoming Wildfire Sense UI. This is an Alpha Build at the moment and there are a few nagging issues, but it's neat just to use for half a day on the weekend to see how Froyo Sense will eventually pan out.

Finally, take a look at some of the Froyo ROMs that are built around CyanogenMod 6.0 (e.g. CELB Froyo; KaosFroyo; Tazz Froyo; and I think ShadowROM). Maybe you'll find that you like CyanogenMod better than Sense and stick with that?

Good luck!

P.S. In the future, you're probably better off posting something like this in the Q&A section.
