Hi Kronok. Firstly, wait for Sponsorship Approval letter as well. Probably it will take a day or two. But wait for that as well.
Then begin your wife's TRV application.
Ties back to home. Dont worry about that. But yes, provide enough financial evidences of your income and confirmation in writing that you will provide for her everything, from travel expenses, to her stay in canada. And if you have evidences of sending money to her right now, then add that in the application as well - that you are even providing for her right now.
Provide your pay stubs for 3-6 months, employer's letter, NOA, etc etc. enough evidence that officer knows the she wont be in financial troubles.
Once she is in Canada, she will be allowed to apply for OPEN WORK PERMIT. If she is educated, has IELTS passed (or another proof that she speaks fluent english) and has some skills/experience that she can get a job (specify job role/title etc), put that as further evidence as well.
So no need to worry about trying to prove that she will get back to her country. IRCC finally got the common sense to accept and realize that when a Canadian Spouse is trying to bring his/her spouse to Canada - generally they are trying to live together.
All the best in your application!
