I'm also in the same situation - I find more info on chewing gum reviews! Anyway, the best I could find is at the following web site: http://www.hometips.com/cs-protected/guides/garage.html IF ANYONE HAS INFO ON STEEL DOORS THAT THEY REALLY LIKE OR DON'T LIKE - PLEASE POST A FOLLOW UP. I hate to spend this kind of money & have no idea on recommended brands. below is the specific info from there on Steel garage doors - very general, but at least it gives some things to look for in replacement doors.... Steel Garage Doors. Steel garage doors are much stronger and more secure than wood, aluminum, or fiberglass ones. Thanks primarily to new technologies in embossing metals with wood-grain patterns, and new durable coatings, today's steel doors rival the look of wood without the maintenance headaches. Steel doors won't warp, crack, delaminate or fall apart because of weather. And, because most are made of hot-dipped, galvanized steel that is vinyl clad or given a baked-on polyester finish, they don't rust or require repainting as often as wood doors. Most warranties guarantee the door won't rust for as long as you own the house, but do not protect against fading. On the downside, steel does dent and can be difficult to repair. Premium-quality garage doors have cores of rigid polystyrene or polyurethane foam insulation. Not only does this insulation help keep the garage warm in winter and cool in summer, but it makes the door lighter, quieter and easier to operate, and less likely to sag or warp over time. You can usually discern a steel door's quality both by its thickness and by the thickness of its cladding. A premium door is often a full 2 inches thick, filled with insulation, and clad in 24-gauge steel. Less-expensive doors are usually thinner and made of 28 gauge steel (the lower the number, the thicker the metal). Doors may be single skin, with a frame that shows from inside, or double skin, sandwiching the foam insulation between panels on both outside and inside. The double-skin construction is much more durable and is attractive from inside the garage. Weatherstripping is another measure of quality. The best-made doors have a full-width vinyl bubble weatherstripping along the bottom edge of the door that conforms to the floor. They also have rigid-vinyl end caps along the sides of the door panels, a vinyl top cap and weather seals between each section. Styles imitate those of wood doors: flush, recessed panel and raised panel. You can also get metal doors with a horizontal, ribbed design. For an average-sized steel door (16 by 7 feet), expect to pay from $750 to $1200 installed. -durk

The moulding should come off, screws, clips,???. We always replaced with plexiglass, that way you only replace each pane once.

on our doors the cables do not attach to the roller but to another plate on the door that the roller is also attach to. this means you simply remove the roller and it's mount, while leaving the cable mount in place. if this is the case, you do not need anything special to do it. if you must remove the cables to replace the rollers, make sure that there is no tension on them. that spring is very strong, and can seriously injure you if the cable pops free. generally, the more bearings you have the less noise. nylon would also be quieter, but they will not last as long as metal. you would get several years out of them, but not likely to get 20+ in my opinion.

If the job is planned out in advance, it should take about one day to remove the door and hardware, frame and install the new door and trim. Painting would take an appropriate amount of time to allow drying between coats. If drywalling is needed on the inside, that would also take some additional time. If you want custom windows or other accent to make up the difference in width between the garage door and the french doors, that would also take more time.
