ok, then just some hints:
- to split a window right click at a border of the window. if you click on a vertical border you can split windows horizontally, if you click on a horizontal border you can split windows vertically. like you see in the appearing pop up menu you can also join them again of course.
- with the leftmost button on a window header you can set the type of the window.
- you got the uv window visible? good! it's very helpful!
best try to make a window layout like in my above screenshot. one uv window and one 3d view in face select mode.
- in the uv window load your textures (image -> open). the texture will get assigned to the currently selected faces.
- in the 3d view window header you can set the draw mode to textured.
- then you can either do projections like in med, or use the more advanced unwrap function (i will explain the unwrap function later).
- to do projections, select the wanted faces, press "u" and select the projection method. also make sure you are in the right view (top, side,...) since many projections types depend on it. experiment with that a bit...
- in the uv window you can select your uvs and move [g], scale [s] or rotate [r] them. to select all linked uvs of a selected uv press [l]. during move, scale or rotate mode you can also input numbers. use [tab] to jump to the next input field. also try out [view -> properties].
i hope this helps so far? if not just keep asking...
