Audio Unit looks like a Core audio concept, but I see that it has many custom configurations, so I'm thinking can I use audio unit's setting on an AVAudioPlayer?
but first, what is an audio unit?
From Apple documentation:
"iOS provides audio processing plug-ins that support mixing, equalization, format conversion, and realtime input/output for
recording, playback, offline rendering, and live conversation such as
for VoIP (Voice over Internet Protocol). You can dynamically load and
use these powerful and flexible plug-ins, known as
audio units"

I am looking for a sample helloworld app (or a tutorial) to develop a video chat using IOS SDK.
Here is a tutorial written by myself that uses tokbox api for streaming and Parse.com for user management backend:
Opentok charges you based on api requests and all 3rd party providers will follow that model. The benefit to you would be you can scale based on demand, with some volume obtained for free. You may have your own judgement though. I do not work for, neither vouch for tokbox or parse, the link is just a guideline.
Try using the OpenTok API. That will make things much faster. Creating a video chat app from ground up will take some time and considerable amount of expertise.

I'm making a iOS app like Talking Tom and unable to record only human voice. It gets so much background noise along with the human voice and hence its not, accurate like Talking Tom.
I wonder there must some record settings be present to use with AVAudiorecorder which would help me in this context. I am just using the default record settings for now with AVAudioRecorder.

The question is how to tell system which UI (images , custom buttons, and so on) to show (i must to have some copies with a lower resolution and other copies with better resolution ), because iphone 3gs has a lower resolutin than iphone 4. UI of app should look greate on both devices. How can i get that ?
Read the Resource Programming Guide section called Specifying High-Resolution Images in iOS in the Image, Sound, and Video Resources chapter.
Your non-retina images should be called image.png (where image is your specific filename). The retina versions should be called image#2x.png. The correct one will automatically be selected.

I would like to implement a project in which the recorded audio s converted into text.
I could do this using mturk where the recorded audio is uploaded and stored some where in cloud and the link is forwarded to the mturk but this would take longer time and it would be better if I could implement anything that does this task instantly and from iphone itself.
Is there any ways to do this ? DO i get some custom framework to work with voice so that it converts the audio into text.
Your best bet is looking at something like
OpenEars
http://www.politepix.com/openears/
You can use that to do speech recognition and text to speech and has some instructions on how to implement with iPhone

can anyone give me sample code to transfer photos from one iphone to another using bluetooth
Your best bet would to use GameKit, which greatly simplifies connecting multiple devices over Bluetooth & transfering data. I can't remember having seen an Apple sample which does that, but it certainly would be possible. This is exactly what GameKit was intended for, peer-to-peer connectivity, not only limited to gaming.
You'll probably have to split the data of the image and send little chunks to the other device, which can reassemble the chunks to form the original file once finished.
