For FT, play the $0+.10 rebuy (without rebuying) as a complete nit until you have $10 or so. Then play the $2+.25 SnG while you have above $10 (if you go below $10, go straight back to the $0+.10). The $1+.25 is just terrible value because you lose 25% of your buy in (the entry fee).
An alternative is to play $2+.25 as soon as you have $2.25 and supplement that with any good valued freerolls
you can find (CC freerolls are definitely some of the best in terms of value).
Finally, cash games is out of the question. You will lose your money so fast unless you are already an exceptional player. I started off at $0, and any money I made in freerolls was quickly lost in cash games but playing strictly SnG's has made my roll grow. Good luck!
