(REDHAT RHT)should i go full 100 % into fidelity small cap discovery or

keep it at 75% for smallcap and 25% for fdelity growth company? i aint liking growth company much right now due to red hat doing terrible, but it also has apple as one of its top investments. Im 40 and have less than 10k in my 401k and just kicked my percentage up to 10 percent of my check. Anything special i should be doing? What if i have say 200 bucks extra each check what should i do with it? put it into my 401k or maybe start a roth or try my luck picking my own stocks on fidelity? i was always told invest into stuff you yourself use or know about..i can only buy so much stock in vodka and marlboro, wel i probably cant afford marlboro lol. anyways thanks for any and all help.
