You do have the starter level stuff then and Mother is a very decent brand. A few more things like an interior cleaner + a detailer and you should be good (considering you're someone that doesn't want to go into too many details). Mothers also has a very nice showtime detailer so you can stay within the same company stack or even get the meguiars ultimate detailer. The detailer will help you keep your car clean (almost like just waxed) between the car washes/wax sessions. Its also required because carnauba wax attracts a lot of dust, so after you've waxed, the detailer will reduce the dust magnet effect. Using a detailer wouldn't come with extra burden. Much like you dry dust your car, just have the detailer in hand, mist spray and clean with the MF. If you're having someone else do it, just let them know to spray it lesser (1 strong mist with a moving hand from a 2-3 feet distance.. For bigger panels like the hood/roof, 2 sprays would do).
For interior you can buy meguiars ultimate interior detailer.
Where do you live ? My office boy (very reliable) goes to my colleague's houses and wash/wax/interior clean it on weekends for a nominal fee. Unless you live in the outskirts of rwp, I can connect him with you if you're interested.
