I am creating a new altcoin and i cant seem to figure out how to disable mining functionality with wallets using the debug console window.

Remove the generate and generatetoaddress commands.

I am trying to mine all the coins myself, is there way to restrict all mining to me or specific IP addresses.

Unless you modify blocks to include IP address information, no, there is not. You could restrict coinbase transactions to have only a specific output script which belongs to you so that blocks that have coinbase transactions where the coins go to another output script are considered invalid. However you will need to modify the mining code to use a fixed script instead of generating a new one for each block.
