Geek Squad "Uber" Calibration - Worth it?

[UlicBelouve]

I have some additional questions on calibration. Just got a new 1080p TV last night (Sharp LC-32GP1U, need to update my signature).

They were also pitching the ISF Calibration done by Geek Squad to me. Now, the demos of the calibrated versus uncalibrated were impressive. However, I do not really want to pay for that type of calibration.

I have the DVD of AVIA Guide to Home Theatre, and started some calibration there. I may also do the Sony calibration off of the Talledega Nights Blu-Ray. I am also planning on getting the Terminator 2 Blu-Ray this week anyways, and I gather that this has a THX Optimizer.

Are these going to be adequate adjustments? I know I cannot compete with ISF calibration, but how far off will I be in terms of quality? I have put together a culmination of tips from this and other forums. So if I arm myself with the following tools, should I be good?

- AVIA Guide to Home theatre DVD
- Sony Optimization from Talledega Nights Blu-ray
- THX Optimization from Terminator 2

Any other tips would be appreciated, I've seen the other forums on backlight settings, noise reduction, and sharpness. If there are any specific pointers for the Sharp LC-32GP1U, that would be appreciated too.

I just want to get the best possible picture without ISF Calibration, but if I will come nowhere close on my own, let me know, and suggest avenues for getting an ISF Calibration (don't have the best faith in Geek Squad).
