[Plugin: Enhanced WP Contact Form] How to completely remove the Enhanced wp contact from plugin?

I wanted to uninstall the enhanced wp contact from plugin, because I was struggeling too much with the layout. After I deactivated the plugin, I installed an diffirent contact form plugin. I added the message with the code (wpcf), and replaced this code with the one required for the new inplug I wanted to use. However this didn´t seem to work, somehow, the message kept showing the (wpcf) code after saving it, eventhough I changed it to the new code. So i decided to delete the message completely, and make new message entering the new code. This also didn´t work, the contact page just showed (wpcf). So to me it seemed the Enhanced contact form, somehow wasn´t uninstalled completely. I therefor went to my FTP and I completely removed the enhanced contact from folder from my plugins. But still, my contact page (which in my case is as category) kept only showing (wpcf).

So,.. I thought, ok, lets continue afterall with the Enhnaced wp contact form, and to my great joy, I manged to improve the layout by adding the below code the the style.css fil:

/************************************************
* Content *
************************************************/
#wpcf label {
clear: both;
display: block;
float: left;
width: 150px;
}
#wpcf input {
float: left;
width: 200px;
padding: 1px;
margin: 2px 5px 2px 0;
}
#wpcf textarea {
width: 350px;
height: 100px;
padding: 1px;
margin: 0 5px 10px 0;
}
#wpcf #contactsubmit {
margin-left: 250px;
width: 100px;
}

After adding this code, I changed the language to Dutch. However, changing the language to Dutch seems to give a problem, because the text ´send me a copy of this e-mail´, has more caracters in Dutch than in English, and therefor covers the small field, that a submitter has to click on or of.

Futher I tried to add a text above the field, by clicking ´adding post´ on the contact page itself. However since I delided the original message with the (wpcf) code, I get an error message, saying I have to retore the message, in order to adjust. This is no option, because I permanetly removed the file in my ealier attemd to uninstall the plugin. also creating a new post with (or without) the (wpcf) code doesn´t work.

The reason I wanted to added the post, is because I want to add some text on the contact page, above the contact form.

So, to summerize,
1)How can I add my post on the contact page, while the original post with the (wpcf) code has been permantly deleted?
2)How can I after changing the language to Dutch, move the small ´ON´ or ´OFF´ field more to the right, so it doesn´t get covered by the text?
3)If I at a later stage would decide to remove plugin after all, how can I make sure to really remove everything related to the plugin?
