You can just click through the screens for Capital Account Information, leaving them blank. Although it is better to keep track of the capital account balances.
A partner's opening capital account balance is generally the value of his contribution to the partnership. Your capital account consist the $100 you put in the bank account plus the value of any property you contributed (computer, furniture, etc.). The other partner's capital account is the $5 plus the value of any property he contributed.
Since you are just beginning the LLC I recommend you see an accountant to get everything set up the correct way.
