Answer 1

Just check in php if 'submit' field is 'test' or 'live'.
<form method='post' action='' id="Form" >
<table class="sort">
<tr>
<td>email address</td>
<td><input type="text" name="emailTest" value="" /></td>
</tr>
<tr>
<td></td>
<td><button type="submit" name="submit" value="test">Test</button></td>
<td><button type="submit" name="submit" value="live">Live</button></td>
</tr>
</table>
</form>

Answer 2

You'll either need to use JS, or one submit button, and a radio button. The latter is a better option, as you can't accidentally submit something to the wrong queue. Also, you should really be using a submit button, not an anchor.
The reason I would prefer the radio buttons is because once you click submit, you're past the point of no return. The radio button allows you to to click the wrong one, and then change it.
input[type="submit"] {
background: none;
border: 0;
color: blue;
text-decoration: underline;
cursor: pointer;
}
<form method='post' action='' id="Form">
<table class="sort">
<tr>
<td>email address</td>
<td>
<input type="text" name="emailTest" value="" />
</td>
</tr>
<tr>
<td>
<input type="radio" name="testLive" value="test" id="test" />
<label for="test">Submit as Test</label>
</td>
<td>
<input type="radio" name="testLive" value="live" id="live" />
<label for="live">Submit as Live</label>
</td>
</tr>
<tr>
<td colspan="2">
<input type="submit" value="Submit" />
</td>
</tr>
</table>
</form>
