There are quite a few possible ways of application for e:
topical, oral/sublingual, injection, and implant...
there is one form of application with a high dose of implanted e and bioidentical testosterone without anti androgen...
the other forms use anti androgens like spiro...
and possibly bioidentical progesterone... theory is it lessens some side effects of e, has some anti androgen effects and helps with some tissue development of breasts ( the last one was reported by some people being even some time already on e ).
Spreading the dose throughout the day for a more steady level might be of advantage.
An orchi might be of disadvantage if someone wants srs later, because less material might be available.
Concerning brows, trimming and plugging might be an idea and might make a real difference for the face...
trimming from the underside might be of advantage to optically lift the brows and shape an arch.
Having them shaped by someone knowledgable might be an idea...
otherwise there are tutorials on how to trim and shape an arch... its possible to do this step by step over some time....
otherwise its advisable to proceed carefully and check the results often.
