depending on your fit level, i'd prolly drop the dough on moving from that triple to a standard or compact double (depending on your geo). at this point I would just upgrade the some of the group prolly not all of it.

or go for some new wheels+tires. at least you can take that to the next bike.

all this is after you've grabbed the basics which I'm assuming you have like: cycling kits, helmet, pedals, shoes, bag w/ utils, computer, etc.
