Advice for newbie on Tube gear

I'm seriously condsidering getting into tubes (valves here in UK).
I saw & heard them once at a hifi show & have been fantasising ever since.
I'm a bit tech illiterate.
I've been offered Sonic Frontiers SFL-2 preamp + SFCD-1 CD player (240V) for US$2200. Cond is v.good, tubes are about 18mths old. I'll probably buy an ss power amp also(below $700 used).
I'd appreciate any advice on what I'm letting myself in for :
How difficult is it to find & change tubes , How will I know when tubes need to be changed , How much will it cost , What else will I need to do (biasing???, capacitor replacing...).
Are tube SF units low maintenance? I don't really have much spare time ,and am easily confused by techy things.
My system : nothing left apart from AQ Diamond X3 i/c's, AQ Sterling spkr cable, and an old pair of excellent highly sensitive (96db), hi-end(ish) French speakers - Helius Sirius II (only a few made in the '70s/'80s).

Sincere thanks to each who's posted a response (5 at the time of writing).
There must be many who've benefitted from these answers (I previously hadn't found all these answers on these forums - simple though they may be, but VERY informative to a novice).
Each suggestion/information has genuinly been helpful to me ... 300B's, Eldartford's experience, Sbanks explanation of the tubes and biassing, the TriodeGuild site, and Viridian's excellent to the point explanation of my particular situation.

I feel that I may be able to tackle the tube buying/replacing fear, and cope with the biassing (not so confident). I'm hoping I may be able to get away with doing minimal maintenance with the tubed pre & CD, and may even look into SF's own power amps (SF80..?).

Meanwhile I'm going for the SF tubed pre & CD (They look so good together I can't separate!).

Many many thanks!!!

Mahandave, maybe it was a general question on tubes. Issues on changing/buying tubes + biassing were answered, as well as other suggestions. I didn't find those specific comments/explanations elsewhere. Opinions were welcomed - sarcasm was not.
