newbie building a stereo system, needs help

[dj_daniel88]

so i've been doing a bit of research, and i found this place:

http://www.carltonaudiovisual.com.au/

they seem to stock a lot of quality brands, and are close enough for me to go and take a look... they also sell monitor audio rs1's which corto maltese suggested.

the room these will be going in is about 9 foot by 9 foot, so its only small. thats why i was thinking i only need bookshelf speakers. i dont know how much bass you can get out of bookshelfs without a subwoofer though, and i don't know how loud these can go without distorting. this brings me to my next question... how powerful of an amp do you think i'll need?

what i'd like is reasonably small speakers (not floorstanding), with a big sound and nice bass... because of the size of the room i thought this might be feasable? ... but maybe not on my budget?

what do you guys think of this set up:
monitor audio rs1
marantz pm4001
marantz cd5001
rega p1

are cd players and amps really that much different? for example would it be worth my while getting a used amp with enough power and phono input to save some money? or get a used good quality, branded cd player?
