hmm anybody managed to sucessfully use the panorama function in the camera after the upograde ? mine always end up error till i got fed up with it ..

Used DoomLord's method on my stock Arc after updating it to 2.3.4 42 using PC Companion, so no, I don't think Flashtool or xRecovery is required (adb drivers bundled with the .zip file you download from the xda-forum links I linked).

Btw I have a question about SE original warranty. Apparently my 4.3" LCD screen is separating slightly from the phone body, allowing some dust and dirt to enter . Could be due to contact between my Arc and my house keys in pocket.

My question is, if I would to bring this problem to Dynamics distributor (where my phone is bought from), would they handle this? How long would it usually take?

I don't deal much with phone warranties and thus very little experience in this

Thanks, I can't seem to find that darn support page. How long did it take for them to change a new screen for you?
I wouldn't suggest installing custom rom if you decide to first root your phone using DoomLord's method because if any need arises, you might have to unroot via his method as well. I fear custom roms might interfere with the unrooting.

But to answer your question, yes, you need Flashtool to install xRecovery and custom ROM on your Android. For further information, refer to:-

xda-forums are a good source of information related to Android development too. Refer there often
