Hi Bogleheads!

I'm very new to investing. I'm 29 year old, maxed IRA and planning to max out 401k this year and invest the rest in taxable brokerage account.

I have been holding all my savings(nearly 100k) in Robinhood to earn 5% interest, but decided to open new fidelity brokerage to start investing better. I would like to

I'm thinking of a 70:30 split between VTI, VXUS.

1) Is it better to split 7:3 VTI:VXUS? 2) Should I go with anything else or introduce bonds too? 3) Should I invest all at once or time it - but, I don't know how to time it. 3) To hold emergency funds, should I use Fidelity money market?

Any advice or suggestions are appreciated for a new passive investor. Thank you.
