Yeah, use Notepad++
It's free, and it's amazing. Or if you can afford it, and you do a lot of coding, or are going to be doing a lot of coding and want a more powerful, easier-to-use editor, go with Adobe Dreamweaver, which is what I use.
But in regard to your question, instead of a blockquote or a br tag, if you want the formatting to look neater, go with a definition list.
<dt>This would be your primary statement</dt>
<dd>This would be the substatement</dd>
<dt> This would be your second primary statement</dt>
<dd>This would be your second substatement</dt>
<dd>Black hot drink</dd>
<dd> white cold drink</dd>
Also, use the W3 HTML validator to check all your work http://validator.w3.org/
