Well is it possible for me at this time to heal heroics?
No, it's not possible. That's part of the reason for punkspider's comment: if you had stayed ret, you'd probably be DPSing 5-mans competently and would be able to accumulate some off-spec gear over time.
The Vindicator Ornamented Boots, Belt, and Bracers and the Neck/Rings of Salvation will be nice complements to your raiding gear. It will be a while before you get serious upgrades to these. The important part for you right now is that they don't require BoJ or faction rep.
If you opt to grind for the S1 gear, you should treat these pieces as placeholders for "real" raid gear, which will include cloth, leather, and mail with better stats. The S1 pieces will boost your +heal and your crit, but leave you fairly gimped for mp5. On the bright side, if you're decked out in S1 at a minimum, you're going to have an easier time healing non-heroic SLab, SV, and Shattered Halls while aiming for that "real" pre-Kara gear.
My guild would take a new holy pally in the gear I've just described because we put a ridiculously low priority on mp5. I almost always have a shadow priest and boomkin in my group, so mana regen is never a problem, and after last weekend's big ZG extravaganze, we now slobber free brilliant mana oil over everyone. Talk with your guildies to see what they expect from you.
Good luck.
