Of course!
As far as books go, some to check out would be The Trans Teen Survival Guide and A Smart Girls Guide: Body Image could both be good starting places, and you could check to see if your library has audio versions of them if reading them doesn't feel like the right call. Depending on how comfortable you feel, you could also go to the nearest library (or search their catalogue online) to see what they have in the teen non-fiction section around puberty, self-presentation, grooming, and that sort of thing.
If videos are more your style, you could see if anything on AMAZE gives you the information you're after (they have a decent amount of content on puberty, which can often go into those grooming details:
https://amaze.org/video/puberty-taking- ... g-puberty/). You could also go even more granular and get on Youtube to search for tutorials or explanations of specific things (for instance, I'm betting if you search "how to care for long hair" you'd get a lot of videos).
For bras, there's a really basic overview of how to pick them and how to care for them here:
Trans Summer School: Gender Expression Gear. I also like this VERY detailed guide from Autostraddle:
https://www.autostraddle.com/the-bra-is ... obs-77172/. Breast forms or inserts aren't all that complicated; they're a piece of material (like silicone) that you set against your chest when you're wearing a bra to create cleavage and to fill in the material of the bra.
As for tucking, here are the basic steps (I adapted them from this guide:
https://sockdrawerheroes.com/pages/tucking)
1. Gather your tucking supplies (tucking underwear AKA gaff) . Put these on and pull them up to your knees.
2. Use two or three fingers to tuck each testicle up into each corresponding inguinal canal. This should not be painful. If you feel pain, stop and try again later. Some people choose not to tuck the testicles up into the inguinal canal. If you prefer, you can position the testicles back and to the sides. If using this method, choose underwear that's wide enough to keep anything from, well, spilling out the sides.
3. Next pull the penis and scrotum backwards between the legs. This should help keep the testicles tucked up if using this method.
4. Put on your underwear to keep everything in place.
Tucking may be a bit uncomfortable, but it shouldn't be painful. If you feel any pain or discomfort, stop tucking and give yourself a break. Try tucking in comfort at home, where you can easily untuck if needed, until you get used to it.
