Hey jzahlaway & others,
This is so simple, don't have to follow such hard steps, I shall guide you with two basic steps.
Method 1: Perfect Image Placement
---------------------------------
1) Upload picture using the inline option, enter title and description.
2) Click on uploaded picture and you would get options such as
* Using Thumbnail
* Linked to Image
* Send to Editor
* Delete
* Close Options

3) So basically all you have to do is, click on the option "Using Thumbnail" which would change to "Using Original". This makes sure the original size of the image appears in the post (in what ever resolution and size you had uploaded)
4) Next click on "Linked to Image" (twice),which would change to "Not Linked", this is what you need when you insert a image in its full size and not thumnail.

Once you had done those both, click on "Send to Editor"
This is the simple and the best way to acquire the exact image as uploaded in wordpress (make sure the image is not very big and as explained by others, you can resize he image - works on FF and IE only).
Method 2: Manual Editing
------------------------
1) Upload picture using the inline option, enter title and description.
2) Click on uploaded picture and you would get options such as
* Using Thumbnail
* Linked to Image
* Send to Editor
* Delete
* Close Options
See this screenshot >http://img252.imageshack.us/img252/152/th13dw.png
3) Click on "Send to Editor", chage other atributes from the window (source code region), in opera you can see the url in the post window, so its much easier to edit, else you have to select the image and view source code to edit.
Again you need some basic knowledge in HTML and if you mess with any tags there, I am sure the post gonna look ugly. So make sure you follow Method 1, which is the best one.
If you have more doubts about using these, throw you questions here.
