Unless your going for a show stopping finish, then all you probably need is a good drying towel on top of what you have.
Rinse the car off well with a hose to start.
Use the Lambswool mitt as mentioned with 2 buckets to wash the car, one with soapy water one with clean water, clean the mitt in the clean water before dipping into the soapy water to wash the car.
This gets rid of most grit and dirt on the mitt before you apply it to the car so saving creating swirls.
Then rinse the car off with a hose.
Then you could use a decent drying towel, this is to dry the car off before applying the wax/sealant of your choice, the Meguiars water magnet is a good towel if your leaning towards their products and Halfrauds sell them, so could get one on a 3 for 2 deal with anything else you need.
Then once it's all dry use the applicator pads to apply the relevant wax/sealant that you choose, do this one or two panels at a time, then use the microfibres to buff it to give the final finish.
Ideally you should use a separate applicator pad for each product, but as you are working on a budget (and the pads come in packs of 2) use one side of one pad for one product and the other for the second, mixing them slightly isn't going to peel your paint off or anything, just try and keep the products to one side.
Once you get started you can gradually build up the kit you have available to use and add to it gradually as you go, but dont get too hung up on having everything you are advised to use to start as you will be spending 100's and get bogged down by all the alternatives.
But once you start down this path I bet you will be back looking for more advice on what you can try next anyway, it's addictive.
