Welcome to the forum.
I'd suggest checking out the sticky in this section "Eight with Weight: A Reading List for New Investors".
From what you are describing - it may make more sense to setup a TD eSeries Funds account & avoid the commission fees. Once there is enough money to qualify for the cheaper commissions (or enough combined household assets to qualify), you can always setup the TDW account later and transfer the investments over.
Or you could go with a cheaper discount broker but if you know you need time to learn & don't need a broad range of choices - the longer you are commission free (assuming small MERs), the better your returns will be.
There's also several threads on CMF discussing the differences between the two TD account, the process to set each up and the pros/cons/experiences of those using other brokerages.
If you like talking to people in person, you might consider joining an investment club or similar. Then too, I've seen libraries run seminars as well as colleges run courses on investing. If you keep in mind the question of "how is the seller/ad visor being paid", you've usually got a good idea of what to watch for/risks.
For the CIBC MF's, you'll have to check if TDW will accept them as MFs (I'm sure the eSeries account won't). Having these funds may mean that a CIBC brokerage account makes more sense. Worst case, you might have to sell them and transfer the proceeds as everyone accepts cash. Make sure to negotiate as sometimes if the receiving institution thinks they are gaining business, they'll pay for some of the expenses.
