I'd say just get out there first and give it a go. And see where it goes. If you wait for the right bike, the money, etc then it'll be some time coming.
There are usually a few race bikes for sale on TM and on here.
e.g.

This I think is incredible value for money. I'm setting a '88CBR 600 up for the track and bought a bike cheap but there are a fair few dollars to spend and time getting it sorted. Then there are bikes that are already sorted.
To get to the track I don't need much;
- the stuff in the sticky and race pads (wired the sump plug, oil filter and set a bottle for the fluids etc)
so far I've;
- pulled the steering head out and cleaned and greased
- stripped the bike down, cleaned and checked (really cleaned with 20 years of gunk gone)
- greased the swing arm
- sold all my plastics (lucky that)
- oiled and sealed the front forks
- new engine oil and tune
- removed the centre stand
Still to do
- add a kill switch
Then what I want to do next is;
- remove and thin down the wiring
- direct wire the fan to a dash switch
Then my list of future work
- find a glass fairing (or get one to fit). If anyone has one that might fit that they want to see the back of, even if it needs repairs please PM me.
- This includes the tail cowling. (I only have a CBR600 seat at present)
Work that people who got into racing might do;
- find rims for bigger tyres front and back
- change the front rotor to 4 pot
- change the front rotors to the next generation
- re jetted
- performance bits
- race pegs
and the list goes on.
A bike like the one on TM probably couldn't be built for that price. I thought there were also some 250's here and on TM as well.
Like people have said above if you talk to racers you'll start to form an opinion of what you want. The 400/4 offers a few advantages. I felt comfortable on a physically bigger bike.
My experience of the CBR 600 so far is that it tracks well and is stable. It is due to make it's track debut in the coming months.
