Splitting Europe and Asia is a kinda old fashioned method, from back before total international funds were available. Most people now suggest total international, or else splitting developed and emerging markets. And what is up with all the growth and technology funds? They are largely redundant. It looks like someone put this together in 1999 ;-). In theory growth funds should underperform "blend" or "value" funds, and do so with a higher expense than "blend" funds. Oh and cash is pretty pointless in an IRA. It is for immediate spending needs only.
There are an infinite number of ways to break this out. A good starting point as you approach FIRE may look something like 40% US stocks, 30% international stocks, 20% bonds, and 10% your choice. "Your choice" could be more in US, international, or bonds, or it could also be something like REITs, gold ETF, lending club, etc. How many slices are you trying to use? Assuming you are happy with your current level of complexity, perhaps:
20% US S&P500 (401k?)
10% S&P400 Midcap (IVOO) (ETF)
10% S&P600 Small Cap (VIOO) (these ETF tickers are hilarious, I hope someone got a large bonus)
10% US Midcap Growth (VMGMX) (hey why not, if you are happy right now)
15% International Developed Markets (VTMGX)
15% International Emerging Markets (VEMAX)
20% Total bond, intermediate investment grade bond, or intermediate treasury.
Of course it is possible to simplify that down to a three fund portfolio pretty easily.
When you are approaching FIRE it is probably best to treat all money as part of the same fund. Develop a plan that incorporates all tax sheltered and taxable money into a single concept. For example, you might want to keep international in taxable accounts to get the foreign tax credit, US S&P500 in the 401k because it is cheapest, and split whatever is left into the IRA's.
What is the expense ratio on your 2045 fund? You will probably be better of using a low cost stock fund and incorporating that into your overall allocation.
