There's a heap of resources on this great site, check them out for info, etc. Depending on your hair/skin type laser can help to permanently remove body/beard hair. If not suitable there's always electrolysis for the beard (permanent) and maybe waxing for the body (not permanent but a longer lasting solution to shaving and thins the hair). I'd suggest being on HRT for several months before coming out at work, plus try and find a gender counsellor/therapist, they will hopefully be invaluable.
