OK, I haven't washed my hair in almost 6 months, rarely wear shoes, and have 1 fingernail that is a centimetre longer than the rest, but I do have some good tips.
A hairdressing kit comes with a lot of useful shit, especially the electric razor and mine came with a mini one for beard trimming, etc.
I use the electric razor on my chest and stomach, I don't bother shaving it all the way anymore, still neater than nothing though.
The electric razor is also good for legs and armpits if you like, gets the hair very short without having to shave it all the way. If you're prone to getting ingrown hairs FFS don't shave your legs with a normal razor, fucks shit up.
Lavender oil is awesome for everything, put some on a cottonball and apply to a pimple, cut, scar, ingrown hair, etc. Make sure you buy quality shit.
A quality microdermabrasion cloth is good for improving skin tone, removing dead skin, preventing wrinkles, and lightening scars.
If you have a unibrow use tweezers, but don't go crazy trying to shape your eyebrows too much or some stupid shit.
* For dick and ball shaving - once again the electric razor comes in handy. Use it the first time to get the hair short, careful on the sack. Then run a hot bath and soak for about 15 mins which makes the hair softer and less harsh. While still in the bath, shave. I just use a disposable double blade razor, but anything works. Then after you're dry apply some regular moisturiser. Never had any problems with this method, usually do it once or twice a week. If you start to get some irritation, use lavender oil.
Have fun.
