Can someone give me a clear discribtion of the position of solids, liquids and gases in the periodic table, and description of how the metals, metalloids, and non-metals are organized in the table.

Solids, liquids an gases are not necessary organized in a certain pattern in the periodic table, except perhaps for the noble gases, He, Ne, Ar, Rn, Kr and Xe which are all gases at ambient pressure and temperature. The physical state of an element will depend on temperature and sometimes on pressure. Of course some physical properties of elements are related to its position in the periodic table, but it is coincidental because of the molar mass, radii, and other atomic phenomena (higher atomic number results in higher atomic mass and frequently, but not always, higher density). The periodic table is more related to the chemical properties. The more to the left the element is located in the table, the more metallic behaviour. The elements located to the right are more electronegative (non-metallic). to the center of the table these are the transitions metals, elements that show metallic beaviour but moderately reactive... also the elements in the upper rows are more non-metallic, and electronegativity decreases as the position in the table is downward. metalloids (Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, etc) are a special group, which are in between metals and not-metals, and combine some properties of ones and others (i.e. covalent bonds, and positive and negative valence as well). Some chemist consider metalloids a subjective or non-existent group, but that's a different story.
You may wan to see the following and get a more detailed explanation (and more precise):

gases are noble gases (last column) and and the first 2 elements of the second last column (F + Cl)
liquids are Hg and Br
the rest are solids
metals are the in left portion (first and second columns) and the middle portion( the box in the middle)
the box on the right contains non metals and also metalloids. usually non-metals are to the upper right of that right portion.
