I am going to try and assist you with the issues and inquiries you've stated, please read below!
Notifications (Default, Email, etc):
A ringtone is an audible event notification, such as a sound effect or a snippet of music. You can specify default ringtones for incoming calls and text messages, as well as set person-specific ringtones for anyone with a Contacts record.
Setting the Default Incoming Call Ringtone
Unless overridden by a personal or group ringtone, the default ringtone plays to notify you of an incoming call.
On the Home screen, press the Menu key and tap Settings.
Select the My Device tab, and tap Sound.
The Ringtones dialog box appears, showing a scrolling list containing all built-in, created, and downloaded ringtones. Tap a ringtone to play it. When you’re satisfied with your choice, tap OK.
Setting the Default Notification Ringtone
Unless overridden by a personal or group ringtone, the default notification ringtone plays to signify new email, a text message, a missed call, a waiting voicemail, or an upcoming Calendar event. Unlike call ringtones, notification ringtones are brief and less intrusive.
- Perform steps 1–2 from the previous task (“Setting the Default Incoming Call Ringtone”).
On the Sound setting screen, tap Notifications.
The Notifications dialog box appears, showing a scrolling list containing all the notification ringtones. Tap an entry to play it. When you’re satisfied with your choice, tap OK.
Unread Emails: Before I can help you with e-mail issues -- what e-mail domain/organization do you use? Gmail? Microsoft? (Hotmail, Live, etc)
Voice Commands Inquiry: As far as Voice Commands, Samsung Galaxy S Voice would be the closest thing to that, its similiar to iPhone's Siri but not quite as good.
To launch S Voice, just press your mobile device’s Home button twice. Or assign a voice command to wake your phone and launch S Voice.
Choosing between iPad and Tablets: When choosing what tablet/iPad or devices alike that you may want, there are many factors but an iPad is much different than an Android OS tablet. An Android tablet is more "versatile" in comparison to an iPad. Now a tablet versus other tablets there aren't much differences. Check out the links below:
