I’m going to answer my own questions because I’m a boss like that.

1) To remove image border: In style.css

img.alignleft,
.alignleft img,
img.aligncenter,
.aligncenter img,
img.alignright,
.alignright img {
box-sizing: border-box;
padding: 5px;
border: 0px; <————- set the border to 0px
}

2) To change parameters and size of quote block use these settings in the text of your post editing area:

<blockquote style="width:58%;float:left; margin:0 0 0 0px;">
Note how the width has been changed to be only 58% of its container.

Yeah, I answer my own questions. Wanna fight?
