Questrade is fine. If you're already set with TD and don't have a stack of money, eSeries is fine (probably worth switching in an RRSP so you avoid foreign tax, but again not til you have a reasonable sum of cash).
Credit cards... you need to say what your spending pattern is. There are some awesome sign up bonuses, but ongoing you probably either want a free card (PCF one if you shop at Loblaw-owned places), if you spend enough generally the MBNA RWE is good (flat 2% everywhere), or if mostly at gas/grocery etc, either of Scotia's Gold Amex or Momentum Visa Infinite (4% in those categories) - for the last three you have to offset the yearly fee, but you get travel insurance and so on.
Phones... well, again, you need to specify your usage. If you just need to have a phone, Speakout/7-11 is the cheapest. If you can do VOIP services, Fido is doing 3Gb/$15 which is awesome (direct calling though, it's $1/min... use Skype or Fongo or whatever).
*Edit* - oh, and the obligatory "if you need signup referrals, I'm your anonymous internet person". Don't apply for anything without checking whether a referral will get you a better offer - in terms of credit cards.
