When I first started converting I only knew how to select one vertex at a time, so hopefully I can save a few people from the pain....so I will start with selecting stuff: To select a single vertex make sure you are in "edit mode" and "vertex select" should already be selected, if not, select it. If all of the vertices are selected when you enter editmode (everything will be bright orange) hit the letter "a" on your keyboard to deselect all. Now left then right click on a vertex to select it. It will light up. A single selected vertex: To select an edge start in edit mode, and chose edge select. Left then right click an edge to select it. The selected edge is white here: To select a face, start in edit mode and choose face select. left then right click on a face to select it. The selected edge is bright orange: While in edit mode and using face select, you can hover your cursor over an area and type the letter 'L" (do not capitalize it) to select the entire side: You can draw a box around a specific area that you would like top select. (I usually prefer to use "wireframe" when I do this, but you can choose the viewport shading that works best for what you are doing.) In edit mode, type the letter "b" then left click and drag the box over the area you wish to select. Let go of the button when you are happy with where your box is. You can make a more specific selection if you hold control + left mouse button to make a circle around the area you wish to select. When you let go, the area you had boxed in will be selected: You can hover your mouse over "islands" on the UV map to reposition them in the case of unwanted overlapping. You can also use the box or circling methods above to move things around on the UV map, I hope you find this useful! Happy selecting!
