Simplifying WordPress Media Upload

Hello all.

I’m hoping you could give me advice on the best way to simplify the WordPress Media Uploader.

What I’m looking to achieve:

1. I only want the uploader to allow uploads of images (jpg, jpeg, gif, png) and not audio, video, general media, and only 1 image at a time.

Note: The answer to above may be here: https://wordpress.stackexchange.com/questions/8107/limit-image-upload-to-one-and-disable-audio-video-and-other-document-file-types

2. I want to remove the ‘From URL’ and ‘Media Library’ both visually and remove the functionality.

3. I want to strip out the ability of the user to ‘Insert Into Post’, so when the image is uploaded, it simply says ‘Complete’.

I’ve created a small plugin to include my own stylesheet to the admin section, but ideally I would also like to edit the HTML to remove the code I don’t want / need.

Thank you for any help you can provide, I’m been struggling with this one for a while and can’t seem to find an easy way to use remove_filters or remove_actions to achieve what I want.
