The items you have listed are the items you would need. The only item I do not see on your list is a CO2 cylinder, so I assume you either have this item or will be purchasing it locally.

The 3" column tower you chose is insulated, comes with a gasket and mounting hardware, as do all the towers we offer. The tower you chose has 5' long beer hoses with hex nut fittings on the ends for connection to the keg couplers. The towers with the bent tube assemblies are not very popular. They require purchasing beer hoses separately to connect the tubes to the keg couplers. We suggest staying with the tower you have chosen.
The 1651 flexible hose is used in these commercial grade kegerators to create a continuous cold air circulation within the draft tower. This feature is one of the major difference between the less expensive residential grade units and the commercial grades units such as you have. The cold air circulation within the tower maintains the 36-38°F temperature that is ideal for dispensing draft beer. In the less expensive residential units, the lack of this integrated blower allows the beer in the beer hose within the tower to exceed the 36-38°F temperature. The temperatures above 38°F will cause foam and promote sour/cloudy beer. When temperature rises above 50-55°F, bacteria growth rapidly begins to spoil flavor and cloud the beer. Simply put, keg beer storage can be compared to milk storage: “if it is not kept cold, it will spoil.”
Most keg couplers have a standard hex nut fitting on both the gas port and the beer port. When switching between keg couplers these is no need to cut hoses or even remove clamps. It's a simple matter of loosening and removing the hex nut fitting from one keg coupler and attaching them to another keg coupler. Only the home brew (Home brew beers) and twin probe (Micro Brewery beers) couplers do not use the standard hex nut fittings.
The hand pumps cleaning kits have a brass faucet adapter attached to the hose on the bottle. These kits come with detailed instructions that explain the steps involved in cleaning the beer hose, faucet, and keg coupler. The process is quite simple takes less the 15 minutes.
Step one is to shut-off the gas supply.
Step two is to loosen and remove the gas hose and beer hose from your keg coupler.
Step three is to please the keg coupler and end of the beer line in a bucket or pan.
Step four is to use the included faucet wrench to remove the faucet from the beer tower and place the faucet in the bucket or pan with the keg coupler and end of the beer line.
Step five, fill the cleaning bottle with water and add cleaning solution.
Step six, attached the faucet adapter on the end of the cleaning bottle hose to the beer tower.
Step seven, pump the cleaning solution into the beer line and let it soak for the time prescribed by the manufacturer of the cleaning chemical.
Step eight, fill the cleaning bottle with water and pump it through the line the rinse away the cleaner.
Step nine, (the most often overlooked step) the keg coupler and faucet have been soaking in the cleaning solution and rinse water so any residue from the draft beer left on them will now be softened up. With the nylon faucet brush that is included with the kit, brush off the keg coupler and faucet then rinse them clean with water.
Step ten, reattach the faucet to the beer tower and the keg coupler to the gas and beer line. And turn the gas supply back on.
These steps in the cleaning process may sound as if this is quite a lot of work. But in actuality it take only 10-15 minutes.
