If your starting from scratch I'd say make sure you go for a charger that can do LiPo/LiFe/A123 cells so your a bit future proof but then go and buy some proper cells, just my opinion though.

all of my setups use a 4900 lipo with minimal weight added. it has allowed me to make the car very supple across the bumps whilst still landing even the mega jump at worksop silky smooth everytime.
as already said have a look in the second hand section on here as there are the losi systems that seem very good value for money and also the second hand lrp/ nosrams are very good as well and have a very good warrenty system so that you can always buy in confidence even if it is second hand. depending on how much experience you have from your previous racing will depend on the motor id recomend. if you wernt the best racer in the world then start with 10.5 (sameas an old 19turn) this will make the car a lot easier to drive so that you will break less and wont be much slower than a 7.5 or 6.5 in a straight line.
as for charger and cells. personally id go the lipo route.
1 the cells need less maintenance
2 you dont need as many cells
3 the speedos above all have a lipo cutoff so you wont take the voltage to low
4 what ever cells you leave for a long period will self discharge but the lipo will do it a lot less than a nimh will.
if you are woried about leaving a lipo for a long period then get a charge pouch ( £10 )as these will reduce the risk if the unthinkable does happen.
lipos are a lot safer than nimhs. in the 7 monhs that i have used them and also in the last 2 years that my local club has used them there have been no flame outs etc that you see on youtube etc but i have seen at least 20 nimh's packs explode either in the pits or on track so ignore a lot of the scare mongery that you will hear
having said that go to
www.brca.org and look up the electric board so you can find the list of brca legal lipos and nimhs and also safe charging advise etc etc
as for charger the bc6 seems to be a popular choice and it has a built in balancer or if you are on a tighter budget look at the flightpower/trackpower unit(both the same. one black one gold). small compact and easy to use as well as being cheap although bare in mind that you will need to purchase a balancer as well unless you have a race friend who also has one.
mark christopher will be able to give lots of advise as to how to treat your lipo for maximum life so look for him on oople as he is a very helpfull chap.
As for rb5 setups look in the setup section on here or feel free to pm me any questions you may have, as a beginer dont forget to stock up on spares. all cars have a weak point or 2 and the rb5 is no exception. personally to date have broken
front c hub
rear T-piece
but as a precaution i also carry wishbones, shock towers, all hubs and the above bits
