It's good that you are aware of financial issue in early stage. You are far too early to worry but preparation is always good.

My suggestions are similar. Build any facilities non-stop and buy younger players if possible.

I used to occasionally stopped building stadium because at that time I thought the ticket sales proceed was low, and I tended to use cash on buying high quality players as the auction market in those season was suddenly very very easy. In fact, for maintaining long term financial health of the team, building facilities should be in top priority.

Besides fast growing, advantage of buying young players is prominent increase in market value with time (for low levels).
