Text Book Recommendation: Cell & Molecular Biology + Organic Chemistry
Given your requirements I would go for the Alberts for molecular cell biology.

For organic chemistry, in my opinion, there is no better book then the Clayden. It is targeted at OC students but I - as a biologist - learned a lot from it and still sometimes love to browse through it even though my work is far away from organic chemistry.

In general, I would advise you to go to your local library and take a look at the different choices before getting one. Take your time to get a feel for the writing and teaching styles and pick the one you find most access to (and maybe give feedback as a comment/an own answer to your post which book you took and why, for future reference).
