the specifics are fine, but the context isn't...

As to No. 2: It is a Mac OS security feature called Gatekeeper. Go to System Preferences > Security&Privacy > General tab and you can change your options there (however, it is not a good idea to override the security features permanently because a lot of software may include unwanted additional malware put there by dubious sites); see the article here:

OS X: About Gatekeeper - Apple Support

If you want to override it once, simply control click on the installer and let it install.

Someone else will need to chime in for #1.

For the terminal question, if you post in Mac OS X Technologies there is a category "unix", I think your question is more likely to be answered there. And I don't understand your question. "bash" is the default shell for terminal, what problem are you trying to fix?

1.My Terminal comes with bash 3.2$ instead of defaults. I did check bashrc, bash_profile but still it remains the same.

The default prompt should be the hostname: CWD user

A prompt of bash 3.2$ occurs if you run bash as a command. With the terminal open look at Preference->Profiles and select the profile you are using. Select the Shell tab. Is there anythgin set in the Startup Run Command field (most likely it is set to bash) clear it out.

Well, if you don't want to override Gatekeeper and don't want a one time exception, then you cannot download the software. Depending on what it is, that may be a good thing as it is probably safest to only download software from the app store.
