I print on an R3000 as well. It's fine with LR, however, you must be aware that LR is not able to soft-proof in CMYK as photoshop do. I had a profile made in RGB which helps a lot, for no-so-difficult prints I usually get it the first time (calibrated IPS non-professional screen)... and it's not a big problem as long a you print locally. But for example, if you order a book with Blurb (which is an adobe partner and from which you can order directly through LR), they only proviude a CMYK profile... which LR can not read.
Otherwise, as said by others, is you were satisfied with Aperture the obvious choice is LR, Photoshop is clearly for more advanced retouching and IMO as far as RAW developping go Lr is enough. Also, it's not a cataloguing software at all and most people I know or read use a third-party software for cataloguing, or LR.
