no problem, man..i just joined the local bonsai club this month, so i'll probably be getting my knowledge on a lot this year. i'd probably try to let it ride out the winter if possible at this point, just because when you repot it's going to stress the tree and with the harsh conditions just won't be good if it's already stressed like that. are you familiar with mycorrhizae? that's my other concern. most times when you repot a conifer or evergreen you want to take the old soil and mix it with some water and then pour the liquid over the top of your repotted tree to make sure that the beneficial (i think it's technically a fungus, but the two have a symbiotic relationship that helps the tree get the most out of its soil) business gets reintroduced. at this point i'd just let it ride and see what happens with a repot in the spring. bonsai is a great patience builder that way. and if it dies, try it over again. i've learned something every time i've killed a tree.
